Not sure if you are familiar with FrogForum.net but it is a similar site but has this cool REPUTATION option. /I'm really bad at explaining things but it is worth looking at. It helps members know you is knowledgable on the site. It is completely different than just liking a post or thanking someone.... it is only clicked when someone post accurate and helpful information. You can also take away rep if someone is posting dangerous or inaccurate info or causing issues. I always look at a persons Rep when they answer my questions as I feel I can trust and rely on those with more REP bars under there name.
