I edited many signatures.
I am talking about commercial signatures.
But anyway the signature should be with no more than 3 lines and if we see the post so the must see the message inside the post first and than only we should see the signature.
But some members are doing very big colored signatures and posting just "Thanks you" message only. Just to sho the signature.

No direct signature promotion sorry.

Everybody knows that other forum links are allowed, signatures are allowed so use it without insulting the other members.
