I have a suggestion for any forum that deals with job offers. How about locking posts that are more than a month old?
When I come to the forum I browse thru most of it. The only places I don't check very often are: software development, tech talk, and coffee house. Otherwise though, if there is a new post I see it. It usually takes me 20-30 minutes to look through everything (yeah I know I don't have to) and that's if I'm not responding to posts (I try to help :)) So, when I look in the "Webmaster / Designer / SEO Job Offers" forum and find that someone has replied to posts that are over 2 months old, it irritates me that I took the time to look. Honestly, if you reply to a post about a job from 2 months ago, do you think you have a chance at getting it? No you don't. You are just spamming. AAAAYYYYEEEE!! maybe I should get some sleep.
