Who knows how github works with tracking participants
Dunno about that but I can hazard a guess ... they are context-specific views, the same 18 forks viewed from different devs' perspective:
https://github.com/vertoe/spreadcoin/networkhttps://github.com/spreadcoin/spreadcoin/networkhttps://github.com/spreadcoin-project/spreadcoin/networkhttps://github.com/gjhiggins/spreadcoin/networkhttps://github.com/bitbandi/spreadcoin/networketc. Lord knows where it gets 18 forks from but that total is common to all of the gh SPR repos, the fact of that consistency probably has a meaning.
I can't find the darkcoin fork, but I can find the initial commits and they seem to start with Vertoe, or he has forked spreadcoin somehwere?
You won't find the Darkdoin fork as such, Spreadcoin was a proper fork in that the prior DRK commit history was not carried over (which it would be in a clone) so there's no reference to darkcoin contributors in spreadcoin's commit history.
Yes, vertoe used GH to fork spreadcoin at some point after 11 Feb, its position in the push-down stack on
https://github.com/vertoe?tab=repositories suggests that it was done quite a while ago. No surprises there AIUI.
