Tags For Tagging: Pre-Select tags most used in forums
 

If I see a tag and I'd like to tag it: What tag name should I give him?

Give the user a list of tags most used in the forum so he can just click on it and its done.

Example: In this forum suggestions there are tags mostly used: style, admincp, posting. Next to the tag box in every thread of this forum, these tags are displayed, so the user can tag the threads with just one click.
