My tip is to get in the contests when they are still new and not many contestants :D I remember winning @bengy's Steam Key giveaway contests a couple of weeks in a row and feeling bad about it, but not anymore since there are so many contests out there... just check @artz's list for a sample :)
and that is what I'm doin at the moment searching for more contest hope to have some shine and get to know with each others .. Thanks for the tips... Have a nice day @plushzilla I think I saw your name somewhere too out of Steemit hmmm
