@pennsif
@portraitcontest weekly portrait contest
@teamserbia weekly photo contest
@brumest has a monochrome photo contest, it was daily not sure now
@worldcapture has a contest that i totally missed
@czechglobalhosts has a 7 World's Continents Photo Challenge every day different continent, and it is on for ages
adding @photogames maybe they will start again, but most of them are doing something more important on steem, so maybe it is better to not start it again
i am sure that i forgot something :D
