So, a quick question to the community!

Not many people seem to be donating and I need to generate enough to at least pay for the VPS. I don't want to add advertising to the site, although Google ads would probably generate me quite a bit. Does anyone have any suggestions for generating donations? I suppose I could make it optional on the new transaction page to donate, or throw up a message now and again.

What do you all think would be least intrusive?
