Reputation
Ok, I have added reputation for the forum, to use this feature.. after someone has made a useful post and you wish to thank them, click the + button on the message and it will turn the post green in the corner. This will also increase your repuation on your profile.
Alternatively, if you do not like a post..you can press the - button on the post which will decrease a person's reputation and turn the post red in the corner.
Thanks..
Admin
