how can i make signature of my profile?
i am member since 3 weeks ago...please advice
At the moment, you can only have a signature if you've been a member for over 90 days. http://www.sitepoint.com/forums/faq.php?faq=youraccount#faq_signatures
However, the forums will shortly be moving to Discourse software, which makes no provision for signatures, so after that nobody will have one. http://www.sitepoint.com/sitepoint-moves-to-discourse/
In the meantime, if you need to know anything else about the forums or your account, you can check the FAQs/rules.
Thank you!!!i want to stay this site
you gotta wait for sometime in order to have signature
No. Those currently with signatures will no longer have them by the end of the month. Those who signed up in June (or more recently) will never have a signature.
Thanks Stephen, that sums up the facts very well.
