Yes, but to give you more specific help we need to know what client you are using.

You want to sign a message with your address (more correctly speaking, your private key)?
Or you want to attach a message to your tx?

I don't think he means signing and verifying messages.

I think he wants what blockchain.info supports messages in the blockchain. You can do this with blockchain.info wallet but it is only visiable on their site, it isn't a feature of bitcoin.

He could use OP_RETURN to include a short message on the blockchain (not the site blockchain.info), but he will need to play with raw transaction (please be extremely careful!).
You can see people have been doing such thing already. http://coinsecrets.org/ :)

I think nearly all of the wallets includes the feature of adding a message to the transaction. Note that you cannot remove it, it will be permanent to the blockchain and everyone can see it.

You are mistaken. This is not correct.

None of the wallets provide any user interface for adding messages into the blockchain.

I can include a note in the blockchain.info transaction. I don't get what you mean.

That is not "permanent in the blockchain".

That is a service provided by the blockchain.info company.  If you use their wallet, then they let you create a message that they store in their own database and they display on their website.  This is not a feature of bitcoin, nor of the actual blockchain.  You cannot create those messages with any wallet except blockchain.info

Oh I see, sorry for the confusion, thanks for clearing that up.

Are colored coins (e.g. coinprism) store a message that indicates the color?

Outside from blockchain, can other wallets like btc qt do the same?

If so, where is this option?
