You've probably heard about the full-page Firefox ad that will be in The New York Times and wholly funded by donations from the community. If you haven't, you probably don't read Slashdot, c|net's news.com, and I'd imagine a good number of news sites, in English or otherwise.
Anyway, I was a little slow on the uptake myself, and have only just made my donation (of USD30) that goes towards a one of my favorite causes. If you're a student, you can get your name listed for just USD10.
If you'd like to make a donation, and if you go through my donation link, I'd be branded a Community Champion and get some extra perks (best of which is a free Firefox t-shirt signed by the Firefox crew).
By the way, would a US resident kindly inform me when the ad is taken out? I'd like to buy a copy of it for keepsakes. Would have to go hunting for a copy.
