How to post url link in yahoo answer...i have 278 points level 2,but i can't post my link?

Yes, you can post a link. It will not be a live link though, until you reach level 3.


When can I post active hyperlinks?

Yahoo Answers uses a point and leveling system, based on trust, to protect the community against malicious links and spam. The ability to post clickable hyperlinks is dependent on your level.

Level 3 to 7 - URLs posted are live and clickable.
Level 1 and 2 - URLs are still visible but not clickable. To access these links, you'd need to copy and paste the URL into your browser's address bar.

Only access links that you're certain are safe and not a security threat to your computer.

You'll have to wait until Level 3 before your links are clickable. Users in Levels 1 and 2 can't do that because they maliciously spammed this site with harmful links and can no longer be trusted to do so.
