i will look at enhancements for donators (is that a proper term?). i certainly like the idea of acknowledging those who have donated with a title on their account or something. i just have been trying to keep this site as open as possible so haven't wanted to block attachments and such.
i added a donation function to the main page a month or two ago. a few have found it. every few bucks definitely helps. it uses Paypal. all funds are directed back to the site and spent so i can avoid paying taxes on it.
