How to sign a message with my adress?
Just open your wallet, search for "Message signing" under Tools. Enter the
Wallet Address to use (maybe optional when only one address in use at your client),
enter the text (and maybe Wallet Password) and you will see a signature.
Here is a sample from my BTC address made with the BTC MultiBit client on a Mac:

So the message "That's how it works with MultiBit." signed with the BTC address "1trepexmYrWohyZZUxzyJ3TikbKR2ESAy"
has the signature "G64F3kZhe9uX0GfIRmqHC4rkjeaY6XthvWHTLjoJ/0Rmv9kXtuQZ0DRAUDuMO79xKQm+4uTogaNwHXkB4vYSRag=".
(You can verify this in any Bitoin client but not the LTC client.)
