I noticed you don't anymore post your contests in this thread and I think that's is wrong because in this section more people are active meaning more will join your contests. Honestly I don't regularly check games and rounds section and I almost missed your last contest because of that so I think it would be a good idea to also post your contests here to bring more participants.
They just have to post links here to the promotions and contrst which they are holding in the games and rounds section. People usually visit this section to get info. It is a good idea to have it post here also.
