Wonder if anyone can suggest site/sites to look for bounty campaigns?
This site is what you are looking for.
Go to Alternate cryptocurrencies then click Marketplace ( Altcoins ) then Bounties (Altcoins) Or click this link https://bitcointalk.org/index.php?board=238.0 it will direct you to the bounty section. And search the list below which project you want to join. I hope I helped you
