I'm new to this subforum, here's what I got from the various sources: I reserve a sequence so I'm reasonably sure no one else wastes CPU on it. Upload results to factordb from time to time. If it merges (already known big factors should give a hint, I suppose) or terminates, post on the relevant forum. When I don't work on it anymore, release the sequence. Please correct me if I got something terribly wrong.

You got it right. Have a look to the [URL="https://www.rechenkraft.net/aliquot/AllSeq.html"](in)famous blue page[/URL], too, if you didn't already (we think you did, but just in case). There, all reservations and progress are accounted.
Happy factoring (we've seen your posts in yafu thread, it seems you know what you are doing...)
