What if there was a button or something that you could hit to "second" someone's notion? I'm thinking something similar to the thanking system and the displaying of user names. It is sometimes pointless to make a post saying "I agree with [enter user here]" and people might be able to show more support for certain ideas by seconding a post.
This would be helpful when many different topics come up. For example, if a husbandry issue was brought up and two people post different husbandry specifications, there might be a difficult time seeing which method gets the most support. The "support/second" button would help show what gets more support, and who is supporting it. If an advanced herp keeper is giving support for someone's husbandry, it may be considered more of a valid opinion to some.
I know this is really similar to the thanking system, but sometimes thank you's are not appropriate and this would be. This might seem like a little too much change for the reward that it is worth, but I would rather have this system than the thanking system (no hard feelings).
