No offense, but I know they are. If there is a admin where he dont check just incase a mod did somthing wrong than. Wow!, in my forum I always see what people do with the log.txt
plus, he has to mainten the server. check the hardware (I think) etc... In a long run its hard work. And I look at hes profile and I see hes always PM everyone That is hardwork of typing!
My friend has hes own forum and he pays 10 dollors a month. But not alot of people go on it only one time there was 20 people on for a hole day and that bumped hes bill up a few dollors, now think about davids bill?
