Another thing with reputation. I understand why it is that you have to spread around rep points before giving to people again, but it does make it hard when I want to give somone points but can't because I gave them points already and then there's no one else I can give to. That person misses out on their rep by this scheme...

It's a protection to prevent abuses (such as starting up a troll and just spam-repping yourself.) You'll just have to find a few other people you like before you can bump the first person again.
