There's also the fact that the 'Give a Damn' system is supporting the site, to the benefit of all of its contributors, not just me. Changing that dynamic could be detrimental to morale.
There are lots of other small things making it very difficult to just update the existing system, not least of which being the same time shortage this fundraiser is trying to relieve. I'd need to make a bunch of changes to a very sensitive money-handling chunk of code, which requires careful coding and testing.

I have a series of decreasingly appealing follow-up plans if this one falls too short. But it's already earned enough to get me through at least a few months, so I'll have a chunk of time to take some positive action. Maybe that means I only get 6 months off before I'll have to resume full-time work, but I'll take what I can get.
