No, it's not your incompetence in presenting your case. TBH, the worse thing you guys will do is to stop requesting and presenting your statistics. There are some things that theymos look out to, when your local thread meets such requirements, he will grant you guys a local board. Don't bother to ask me such requirements, because I don't know. Theymos himself will not make those requirements public because if he does, the community will find a way to cheat our ways to beat the requirements.
Well, it is not that hard to find what is required for a local board, a lot of activity and a good number of participants. I guess there have to be some merit sources and then maybe a certain number of Legendary, Hero members and higher ranks in the community. Although nothing of this sort has been shared anywhere, what else can be the criteria for a local board
Also, I think the total number of active members also matters a lot as a local board like this one where there are few members who are doing a lot of activity in the thread. Perhaps they need to increase their active members.
