I added a FC custom token to MEW, but it recently disappeared.  I can't find the information to add it again.  Does anyone have the contract address and number of decimals to do that?  I looked at my tx hash from when I purchased during the ICO, and I tried that address with 18, 8 and 2 decimals (because their website says the go to 2 decimals), but MEW didn't recognize it as a valid token.  Does anyone have the contract address and number of decimals to add the FC custom token to MEW?
Thanks.

Yes, obviously if you have the account and password you can log in any account.  But I was talking about your MEW account, that IF it is linked to you ED account, and if your ED account is compromised, that it's at least POSSIBLE, that your MEW account is also compromised.  The hacker should not have access to your MEW account because he wouldn't get that private key from your ED account.  But, perhaps a very techy person would know a way how to back door into your MEW account from the ED account which is linked to it.  That's what I was talking about and that's why I admitted I'm not techy enough to know if that is even possible.

Yes, that's how you do it.  And, as I said, I too am concerned that if the scammer has access to your etherdelta account, that they could could conceivably access your MEW account.  However, they do NOT have your private key to your MEW account, so I doubt they could log into it  BUT, since they can get into an account that is directly linked to it, MAYBE they could.  At least that's how I see it.  We really need someone more techy than me to weigh in on this though.

But, if your 2 accounts - etherdelta and MEW are linked, and you DID log on to a scam site, then you gave the scam site owners your etherdelta key/password.  With that, they can transfer anything and everything you have in your etherdelta account into one of their own accounts and you cannot undo that transfer.  By doing that, all those ether/tokens will also be gone from your MEW account, obviously.  But if you happen to have some tokens in MEW that are not traded on etherdelta, those tokens MAY still be safe in your MEW wallet.  But like I said, to be safe, I'd still open a new MEW account.

AGAIN, ANYONE WHO LOGGED ONTO ANY OTHER ETHERDELTA SITE OTHER THAN ETHERDELTA.GITHUB.IO SHOULD IMMEDIATELY TRANSFER ALL OF THEIR  ETHER/TOKENS TO EITHER:

1) A NEW MEW ACCOUNT IF YOUR 2 ACCOUNTS (ETHERDELTA AND MEW) ARE LINKED to be totally safe
2) IF THEY ARE NOT LINKED, THEN JUST TRANSFER THEM IMMEDIATELY INTO YOUR MEW ACCOUNT OR ANYWHERE ELSE - GET THEM OUT OF YOUR COMPROMISED ETHER DELTA ACCOUNT ASAP. 

THEN OPEN A NEW ETHERDELTA ACCOUNT AND NEVER USE THE OLD ONE AGAIN.   

There is a way to add your MEW wallet to your etherdelta account, you can search for how to do that online.  But if you don't know how to do it, then you obviously haven't done it, so don't worry.

Yes it's true that the owners of the scam site will only have your etherdelta key/password (again - only if you logged on from one of the fake/scam sites).  But, if it were me, and if I had my etherdelta account directly linked to MEW wallet, I would still open a new MEW to be safe.  Probably they can't get into the MEW account, and maybe even for sure they can't.  But I'm just not techy enough to know that for sure that they cannot.  So, if it were me, I wouldn't chance it and would open a new MEW.    jmo

your friend should be fine.  The danger is that if anyone logs onto a fake/duplicate site, they gave that fake site owner their key/password.  But as long as you only log on o the real site, everything is good.

etherdellta.github.io is back online.  

I fear that there was a hack on this site and hackers crashed it so that they could set up the fake sites through gitNub and etherdelta.com.  For anyone who logged onto either of these sites, to be safe, TRANSFER OUT YOUR COINS AND TOKENS IMMEDIATELY!!  IF YOU HAVE YOUR ETHERDELTA ACCOUNT TIED TO YOUR MEW, I WOULD ALSO OPEN A NEW MEW WALLET AND TRANSFER EVERYTHING INTO IT.  THEN OPEN A NEW ACCOUNT AT ETHERDELTA LATER  ONCE THIS HAS ALL BEEN RESOLVED.

If you logged onto one of the fake etherdelta sites but you do not have your etherdelta account linked to your MEW, then just immediately transfer your coins/tokens into your MEW (and you don't need to open a new MEW).  Later you can open a new etherdelta account.
  

This looks like a huge heist in process to me.  If I were you and had logged into one of the fake sites, I would do as I suggested above, immediately.  Sure I could be wrong, but if I'm not, you risk losing everything in your etherdelta account, and if you have it linked to your MEW, you could possibly lose everything else in your MEW wallet too.

ANYONE READING THIS, DO NOT LOG INTO ANY SITE OTHER THAN THE ORIGINAL ETHERDELTA.GITHUB.IO  UNTIL THIS GETS RESOLVED.
