Let me go ahead and nail down the concerns we'd have from the start.
No, I won't have it run in the background silently with no way to control it.
No, I won't have it start up automatically, users will have to opt-in.
No, it won't be locked in to some high percentage of CPU use, you choose if and what percentage you want to dedicate to it.
Basically completely voluntary, as was our stance on donations in the first place. If you can, you can, great. If you can't, you can't and that's fine, too.
From here I hope to set up the site volunteers we have to get a cut of what goes in over costs, too. I think we'd be more inclined to putting work in for features and anything more than stagnation if we're seeing passive income from it.
Anyway, feel free to voice concerns and we'll talk it out below. Just wanted discussion before I went ahead and made any changes that directly effect users.
Thanks.
