First, don't start throwing tomatoes at me cause I did nothing wrong. I enabled all of the signature, so there's no reason why it does not appear on your profile or attach to any post you made before.

And here is the solution to that problem.

Once you add a signature and click save. (Now don't tell me you don't know how to do that.) Be sure to go to the PREFERENCE page and look for something which says "Always attach signature to my profile". Once you found it, click yes. Then click save.

Please be aware that if you do this after you POST some posts already, your signature will not appear in any of your previous posts. Strange system, I know. But that's the way how things work.

Good luck and hopefully, that answers your question.

another thing about signature is the over-sized signature profiles. It takes up too much of the board (screen) which most of the time it is larger than the members' post.

With this, I wish to imply a new regulation that the signatures are not to be huge and the standard dimension will be released soon.

Any violators will be warned, repeating violaters will be suspended. Previous case of being suspended would earn perm ban if offence is repeated.
