Hello there shockers. We have read your message We try to help you.

We assume you just mean messages. HOW TO?

Sending a message is very simple, I will send you a form explaining how to do it. https://support.mozilla.org/en-US/kb/sending-and-receiving-messages-thunderbird

Signatures are created in Thunderbird's Account Settings interface. Click Tools > Account Settings, and then, in the left panel, select the account for which you want to create a signature.

Here is a form to use to. https://support.mozilla.org/en-US/kb/signatures

Greetings Firefox Volunteer.

In the Composition & Addressing section of Tools/Account Settings for the account, check the box 'Include signatures for forwards'.

Thank you So obvious now you ponted it out!!!

I have managed to get Thunderbird to add my chosen signature to replies but would now like to give myself a choice from several signatures for, say personal or business Write or Reply messages. How can I do this? (The late Incredimail had such a facility).

Sorry about using this reply but I'm still trying to find how to post an original Thunderbird question. How do I go about it?
