I've been advertising a lot lately, and one of the strategies I use is linking back on sites that have linked first here. However, a lot of the sites advertising here are ones I've already advertised on. Since this site lacks a link back sub-forum in the advertisement forum, I have to manually check to see if I, or anyone else, has already linked on whatever site has advertised here so that we don't accidentally post an advertisement twice on other sites. So my suggestion is to implement a link-back sub-forum to help save time for the people who actively advertise for this site.
