After one of the users noted that some of the reputation given is "grey", I looked into this matter, and noticed a lot of the new users have reputation power of 0. This means, whenever they give reputation, the user that has been given the reputation gets nothing. I looked into the program, and it says that "This power is computed via the options you set in the Reputation section of the vBulletin Options. Negative comments from non-admins will receive half this power". It would be nice if you looked into this Grey, and figured it out how to fix it. I can't find this "Reputation section in the vBulletin Option". And add the reputation power of users that are above 0 to 1, above 100 to 2, and so forth. Regards, Jaret.
It's something I noticed - It's not a problem with general settings it might be to do with usergroups, I'll have to look into it a little more - thanks for the headsup though, we've got a few addons (or at least 1) for that kind of thing so the problem could be anywhere. I will add it to my todo list but it isn't a priority just yet.
