Just as a heads up, we are expanding the beta out to build up concurrency a bit, now that we have shaken out some of the initial issues.
A wave of invites is going out for a group of users who have created Runic Accounts at https://secure.runicgames.com/signup
- we will continue to do so over the next few days.
We don't have an explicit number of invites we are sending, but the lions' share of the total invitees will end up from Runic Games account holders.
Edited for clarification - Runic Accounts are separate from Forum Accounts.
