I have never been a fan of signatures, since the early usenet days through to emailing and posting on PerlMonks.

Some people love signatures, some people multicolour their signatures, but rarely do signatures provide relevant information to the message at hand. If you need to add contact details, then do so, but remove them if you don't (is my philosophy anyway).

And sometimes signatures can bite you.. as it seems to have done here, perhaps posting this thread anonymously could have been a more advantageous (in retrospect) strategy..

Just a comment from my experience, it seems word-of-mouth employment is far more powerful than submitting 100+ resumes to online recruitment sites.
