HTML Mac Signature

Hi
I have an HTML signature, which looks great (if I do say so myself). However, I cannot make it stay on 2 computers (iMac and MacBoo Pro). I set up on one in >Libary>Mail>Signatures> etc and it will disappear on the other one.

Any ideas anyone?

Why are you creating the signature on the filesystem? Launch Mail, Preferences, Signatures. Set a signature per account or a global one. Do the same on the other machine.

And, for the record, I don't like people like you. Those signatures irritate me and slow down my experience because I have to download all of that stuff for every message you send me.
