[RESOLVED] How to put signature?

I want to edit my profile and put signature so that every time I post the threads, everybody see my signature.How to do that?

User CP|Edit Signature

And for an Avatar it is:

User CP|Edit Avatar

Basically, the member Id settings that you can set can be found under User CP (the CP stands for Control Panel)

Oh and if you have a signature and/or avatar and they are just not showing up then User CP|Edit Options|Thread Display Options
