Just a note guys...
If you add a signature to your profile it won't show up in your posts, to fix this:
go to preferences (in the profile tab up the top of page) and scroll down until you see a option that says something like always show my sig and make sure yes is ticked.
BTW Reflexes or Macho, as I have previous forum admin experience i know you can change this with your forum tools so that yes is the default to showing sigs in posts.
If you get the chance i would recommend looking into it to prevent queries from new members.
As for signatures, the one below didn't take me long at all (I'm talking about 10minutes including time spent to get the screenshot) and I would be happy to make signatures for people if you can tell me what you want in it.
