I just updated the GIVE link above, since GEM has changed the donation URL. The new system has some issues, I’m afraid. From the most recent GEM Bridges:
At this point, the site works with Internet Explorer but might not work perfectly with other browsers. DonateLinq is aware of the problem and is working to make it equally usable on all major browsers (FireFox, IE, Safari, AOL, Netscape, etc.).
After all my recent browser compatibility woes, I feel their pain. For the time being, if you have any trouble, please let us know.
