-Donated funds accumulate until there's enough to fund one week of
-full time development. The project you specify influences which
-projects receive the most time. Each donated-to project will
-receive attention, even if there's just one donation for it.
-Monthly donations will help me keep doing this for a long time,
-but one-offs are also great.
+As donations permit, I will take leave from my day job, a week at a time, to work on these projects.
