you mean signed message? afaik you can't do that yet.
if you upgraded from the old version you can import the private key to some other wallet and sign from there.

by the way this thread belongs in service discussion.

In the new Blockchain.info I don't believe this feature is possible in the web interface anymore.
You will have to export the Private Key of the address into another wallet in order to sign it. You can do this by following this guide (https://docs.google.com/document/d/1-2l6xOqcbjs9QWEqSh72RD1d8EEdvG_hQuEXw_f_o6w/edit), as described by shorena's thread here (https://bitcointalk.org/index.php?topic=990345.0#post_bci2). You should refer to that post if you have any further questions with signing an address.

Thanks for the guide, I will try it just as an experiment to see if I can get the private key out (have to make a blockchain.info v2 wallet first), though I doubt that newbies who don't think twice about using web wallets will be able to pursue these steps. I wonder if there is a way to do it with the 12 words seed they provide now?

In their code its called "v3", I thought it would be v2 as well.

Im a bit disappointed that they removed signing as well. I hope it will get added and thats is just not the highest priority. Blockchain.info is one of the most popular web wallets and as you say not many will be able or willing to follow the guide.

They are implementing BIP 32[1] so the seed should work with other BIP 32 wallet as long as its in hex format.
