Some people are having a problem adding the signature to thier post.
Try this
On the forum top header click "Profile"
Under the tab header click "Preferences"
Scroll down until you see "Always attach my signature" and check the "Yes" box.
Scroll down a little further until you see "Always allow HTML" and check "Yes"
Then click the "Save" button.
Then click the "Signature" tab next to the "Preferences" tab to add the link.
After you add the link, click the "preview" to see if the logo shows up.
If you can see the logo save the changes.
Post a reply on this thread and see if you can see your signature.
