How to post a tag:

You will need to upload your tag to a photo sharing site, such as photobucket, or pimp and host. Upload your tag there. Copy the Forum code ([IMG] code is the one you are lookin for). Come back here, find where you wish to post it, and simply paste the code in your message! From there it's like any other message. You can add text, center it, whatever you want to do! Hope this helps, if it don't, feel free to reply with more specific questions!
