I have not gotten mine in the pool ... This always appears the error: "No JSON oObject Could be decoded"
I'm using the program GUIMiner.
What can I do?
Start with setting up the Stratum Proxy,
http://mining.bitcoin.cz/mining-proxy-howtoSet GUIMiner to server: solo
host: local host
Port: 8332
username/password - what you find from your info at
https://mining.bitcoin.cz/accounts/profile/SAVE SETTINGS!!! - don't try mining just yet.....
1) start the mining proxy, make sure it is allowed out of your pc/mac/network.... if the DOS window shows no connection, check it's settings, if a firewall is blocking it, etc.
2) on error still, go back to
http://mining.bitcoin.cz/mining-proxy-howto then retry 1)
3) open GUIMiner and start the miner, open it to that tab if you enabled the summery tab ( under view, show summery )
This step is first run manditory to ensure at the bottom it does connect. Subsequent connections, you can either wait for the proxy to be loaded then have the miner checked to autostart OR open it, wait for the proxy to connect and click start.
4) for more than 1 pool, you can copy tabs, set CPU affinity so each tab is only using part of the CPU cycle per pool. This will lower your per pool hash rate and let you mine from more than 1 pool at a time. Repeat step 4 if you have multiple GPUs or want to include CPU mining to get all the hashrate your mining rig can get. Every hash/sec can count!
5) if any weird issues like blank screens, system freezes, blue screen and reboot happen, you may need to clean the northbridge cooler and remove/re-apply thermal paste and/or get a fan on it. I had to do that since one board is PCIEx16 ver 1.1 and the cards are 2.0 and it heats up fast as soon as I start mining.... thank god an old ATI card had the same size fan/heatsink and an old power plug to fan addapter could be made to work on startup to cool the issue.
6) after a week of mining, think how useful this was and consider a donation to me
7) PROFIT!
[EDIT]
some people tend to leave out the full steps such as in this clip

Please make sure that mining proxy ends something like the following, obviously time/date will be different when you start it, if it doesn't contain these lines, ya got issues

from the shortcut the ' startup ' line should look similar to this C:\downloads\guiminer\mining_proxy.exe -o stratum.bitcoin.cz -sp 3333
-o stratum.bitcoin.cz can be one of 3 addresses for Slush's pool, that or -o stratum2.bitcoin.cz -o stratum3.bitcoin.cz
After extensive tests on all 3, I can safely use any of them with my miners, stratum.bitcoin.cz seems to have intermittant connection issues ( max 2 times in 24 hours disconnect having to restart the proxy to connect since it stops finding it )
