Did the site owner, admins, or moderators ask you to do this?
If not, why are you? Especially when the guy whose name is on the door says "About 70 members have donated since I started this "drive." Let's leave it like this... I think if everyone just donates whenever and whatever they feel like the forums are worth to them, we'll be fine. I really, really want to keep the forums they way they have always been - ad free, and the members who have donated so far have made that look like it that will happen."
