I don't see anything wrong with a donate button. People shouldn't feel guilted into donating, but those that feel this is a great site and would like to see it grow and get better probably would like to donate, even if it is a couple dollars. The way I see it is if we had 160 active members and everyone donated $1, you would be set. Obviously the more people donate the faster it will go. I'm assuming that once you have the money you need the donate button would go away? Or heck, keep it there. Considering how much time and effort you put in on the site I think it is only fair.
