If there are still people who'd like to contribute, but can't afford $20, right now, just give whatever you can. The minimum through justgive.org is $5. This doesn't sound like much, but if 50 people give $5, ETS gets $242.50. You can get a computer from Dell for around $300. With what already been contributed, we'd almost certainly be there!

I wouldn't worry about looking cheap, either. If all the members who've posted in the last year just gave $1, we'd probably have more than enough. It's not the individual amount, it's the number of contributions.
