ResetEra will be a separate forum. It was only organized through GAF-affiliated Discords because that was the only place people could hang out over the weekend while GAF was down, when we didn't know if or when it would be coming back, and in what form.
Eventually it will be open to public sign-ups, but I have no idea how soon it will be. Might be weeks. I think they want the confirmed GAF veterans to get in the door first so they can set up the sub-communities properly. When it opens up, there will likely be some kind of e-mail requirement like the one here on GAF (no Hotmail/Yahoo/Gmail), but it's possible they'll waive it for people who confirm their identities through a GAF connection, in case you no longer have access to the kind of institutional e-mail addresses that got you into GAF in the first place. These concerns were brought up pretty early. I'm not the one to ask about this, though: I'm not on the team running this, I don't think the plan for the next phase of invitations has been finalized, and I can't confirm anything.
Asking for invites in this thread probably won't do anything, by the way, at least not yet. But everyone is aware that a lot of people here who were cut out of the loop are interested.
