Thanks very much. I've set before. Maybe it doesn't work since I hadn't post enough threads. Just now I did it again and it is OK.
It takes some time to show. As the forum is huge, it needs some time to get your sig in its database in real time.
For this time, all signtaure links are invisible at outside of the DP membership (without the login). The signature links only be visible to the DP inside membership (must login).
Signatures and live links within posts are not available to users until they have been a member at least 7 days, have positive (green) reputation and have at least 10 posts. http://forums.digitalpoint.com/faq.php?s=&do=search&q=signature&titleandtext=1&match=all when you are making this post, you have only 9 posts. Anyway, now you can set the signature link by going to your setting page
