I've done 18 posts till date but my signature is not active as yet, i have seen users with 2 posts being allowed to put up links on their posts. Kindly, do have a look.
Looks like forgot to check out the FAQ completely- http://forums.digitalpoint.com/faq.php?faq=signatures#faq_signature_requirements 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. So, wait for 2 more days to have signature in your posts.
i registered on 07 Nov, and have 14 post including this , but i also not able to put any link in my signature box. What is wrong ???
You should be able to do it now. Check it once again here - http://forums.digitalpoint.com/profile.php?do=editsignature
To set up a signature go to settings (link found in upper right hand corner of each page) then click on link edit signature.
I registered on 19th Nov, and today is the exact 7 day to approve my self for signature link, but i can't find anything in my CP .
