Looking To Do A Banner Exchange (well somewhat, a few specifications)

Well, my site is a Runescape Private server. I am looking to grow bigger, we have reached about 50 members or so, in the past month. Which is pretty good. We have a site, but are looking for a better host (our old host fell too much) so we will have a lot of advertising space. Our members are pretty active, and we have a game, well runescape private server, which currently hosts over 200 character files, and growing by at least 15 each day. The "Banner" needs to be about 500x500 (ill check again in a bit) so it fits the advert box. It will be on a rotating banner, but it will stay up there as long as ours stays up on yours. Our banner doesn't need to be 500x500, but we prefer in the area of 400x100, or so. Which is a really good deal, as your banner will be shown at almost every update, which is about 4-6 times a week, plus it will be left up there, and it will be in the news archive.I also have another growing site, well I am re-opening it, but I will need banner exchanges here, although I will only want like 1-2 here, since theres about 136+ members that have registered, it will benifit your community a lotThe link to the first one is http://www.enrit.co.nr/

please email me if you have any questions, or just simply post here :)realfbplaya@gmail.com

It looks okay, what banner you need?
