At this time maybe I invite my community friends to join, and ask them to join the competition. And tell them to enter because there is an active posting session about give away here.
Since they spend more time chatting on telegram than on forums, if they did it on forums I think it would be a lot of spam.
But the best solution is to link forum news with official twitter status. between the developer and the community will be connected.
Maybe create community events for all levels, meaning we have communities from different countries. why not create a team show which country has the most active community on radix talk.
Then make a ranking and it will be fair if there are rules or conditions for the competition.
And the winner’s prize can be used as funds for organizing the winning community meet up, at least Radixtalk is the sponsor of the event.
