Resuming: like it was possible to do in Eudora v. 7.0.1. The only option in Thunderbird is: "[ ] Automaticaly insert signature" (in Tools | Options), but, sometimes, I want a signature, other times I don't want any and in some cases I want a different signature, it depends on the recipient, the subject and the character of the message: if formal or not. Reproducible: Always Actual Results: Now, the only option is: automatic signature or not (and only 1 signature) Expected Results: Like in Eudora v. 7.0.1, there should be a drop down list where to chosse the adequate signature to insert. If necessary I have Eudora v 7.0.1 instalation file here to send to you, including registration code.
