Reputation Points...
 

.... I now have three reds, two greens... and a blue. What the heck does the blue one mean?

The blue is neutral. I don't know why it's there, because we have no neutral reputation points.

It's meant to be grey actually, and it means that it's from someone with <50 posts.

Well, Green ones are good, they means that you did somthing good for the forum.
Red means you ticked somone off, so they decided to deduct your rep points.

edit: nevermind

So someone with less than 5 reputation credited me. Uhm... super! :) So does that mean I have to get up to 50 before I can start spreading around red reputation points like poppies on a battlefield?

Posts, not reputation points. As in, the number below your location. :)

You can't give rep to the same person too often. Also you can not rep the same post more than once.

Spreading rep is fun. I've been doing a lot of it lately.

No, you can give negative rep to anyone, even without the certain of amount of good rep points.

I was kidding.... I do see now that it was "posts" not "points". It's a Monday morning, cut me some slack. Wait... it's Thursday? God-dammit........

Lay off the drugs then WW. Then maybe we can all remember what day it is. /joking (I won't make that mistake again)
