Question is, how these funds should be shared? Equally to every contributor or shares based on contribution? I can't find this in mexxer's thread.
From your own quote, that's up to "Lutpin, in coordiation with mexxer-2". Checking 1000+ posts will be a lot of work. I was surprised to see I made 14 posts in that thread (as it was my early days on this forum), but I don't need anything. I guess that goes for more users, and some are banned. This just looks like a loose end that should have been tied up years ago.
As a suggestion that's not much work: pick 10-20 random numbers from 1-1287, use that as the post number, and whoever posted that gets a share (if and only if their post contributed anything and they didn't get banned).
