A DA member asked about this forum's Rep Points. If you haven't noticed these, Rep Points are shown below your username each time you post in the forum. It's below the post count and the date that you first joined.
In summary, Rep Points are the total number of "up" votes that a user's blog comments and forum posts receive. Each person is awarded one "up" vote when his or her blog comment or forum post is submitted. Additional "up" votes require other readers to vote. This can be done by clicking on the thumbs up symbol below the post or comment.
Regarding the purpose of the Rep Points, they currently are not used for anything. However, we are considering a new program which will use Rep Points to help us reward active and longtime members (excluding me ;-) ). It's still very preliminary, but stay tuned for more info early next year. If you have any ideas and/or concerns about such a program, please leave a comment.
