First sorry to post it here, but the reason i'm doing it is the very cause of my problem.
I cannot post on the forums anywhere, except for this very section (PC & Technical Issues).
I had a subscription before, had C-point balance (and still have from time to time) and played hundreds of hours STO,
so I should be able to post.
I have checked my other account, it has no such limitations, so this shouldn't have too.
Yes, newly registered users should have limitations according to the f2p matrix, until meet one of the criteria i have listed before. But I have registered
quite a long time ago (more than a year), so it must have something to do with the transition.
