If you wish to send a donation now that the campaign is over I'll still honor the perks of the original campaign: $15 gets you listed on the donors page and $30 gets you listed in the "Heroes" readme that goes out on all newly created disk images (and also you get listed on the donors page). Your name will remain in those places for at least 1 year (and possibly indefinitely).

If you want to show up on the web site or be listed in the "Heroes" readme then please also send me an email so I know who to credit.
Thanks for your support,
