You are here because your signature doesn't show up on your posts right? what your not?! o.O what the heck are you doing here then....you wont find anything here other than how to get a signature to work so im afraid you are in the wrong spot.
Anyway for those of you that are actually in the right spot and want to get a signature working follow these simple steps:
1. Go to your profile page
2. Click into the tab called preferences
3. Scroll down and tick yes in the section that asks whether you would like your signature to attach to all posts ^^
and you officially should have a signature that will appear on your posts now ^^ (if that is you have made one yet....to do that go to the tab in your profile called signature and make one ^^)
Your signature will not show on your previously posts however sorry about that >.<
Remember no swearing or offensive material in your signatures and keep them a reasonable size....if yours is not suitable or too large you will be asked to modify it. If you do not do so as asked i will simply not let you have one so follow the rules o.k ^^
