No, the forum does the work of calculating everyone's points and win/loss/draw stats.
Arena Mods just have to do the work of clicking "Edit Topic" and then adding the outcomes like "Rilla Won", "Mahz Lost", "Green Lost" for a ranked roleplay. Rilla will get +100 points and +1 Win, Mahz will get +0 points and +1 Loss, and Green will get +0 points and +1 Loss.
Why do you want to be able to directly edit a user's Arena points? There may be a better way.

Or I can just make your @Rilla account an Arena Mod. Whatever works.
Because Melonhead, for instance, has 1400 points. If I were to rejoin the ranks, I'd be up 1275.
I'd rather have the Arena Mod account have it, that way if something happens, I can just pass the account to someone else, and you wouldn't have to remove Mod one account and re-mod another.
