Do you sometimes wish you had a way to really say "thanks" to that person that answered your question? The best way is to give them reputation points. When you are reading a specific message and want to give reputation points to the poster, click on the REP. button (or the scales icon in the basic skin).

This will do two things: Let the poster know you appreciate his work and let others know this person gives good answers.

If you want to highlight an entire thread as something valuable/useful/insightful *or* as something that isn't helpful at all, use the RATE THREAD link while viewing the thread. This will put rating indicators on the thread list for everyone to see.

The more community members use these functions, the more valuable they will become. Thanks!
