Anyone tell me where to edit signatures?

I have digged whole my account area but didnt find any option to edit signatures ..

anyone please?

Also, can i use html in signatures?

you should go to your profile, it is at the bottom from there. and no you can not use html.

yes, i am in profile .
i can see the word Signatures but there is no link around .. i cant click/edit

should be a text area for you to type in, click edit profile

I got that. Thank you
