Do you mean a board or really a thread? Whether which one you are pertaining, one thing is for sure - making any of the two is not necessary anymore. Lots of threads already existed here and Merit System is not a broad topic that's why it is not qualified to have a board.
I support merit system, but every day i came on meta threard and again and again same question about merit and half of them are clear spam.
That happened before when Merit System was recently implemented, there's a time when almost the whole first page of meta was all about merit discussions (so ridiculous, right?). But now, can't you see that our Meta already came back to normal? We get over this already and you should too.
