There's another thread and this is asked and addressed in some of the replies to it. I think a dev says that eventually they plan on a way to invite friends through email.
Yes! eventually we will allow invites by plain old boring email. See my answer here for why thins are the way they are now: beta.glitch.com/forum/gener...
Both of my daughters have been unable to connect to Facebook. I was going to send them invites.... but since they can't connect I can't send them. =(
They are having the same problem I had.... the box pops up but it's empty, the little thing just spins and spins and spins....
They are using their own computers. One is in a different state from me. So, it's not just our ISP or anything like that.
Windborn, I don't think Eric's trying address that — we just haven't finished everything that we eventually plan to do. He's explaining why we did it through Facebook first :)
"Nope: Facebook connect is now & will remain optional (we just use it to make it easier for people to find their friends)."
So I'm not sure what needs clarifying, but there are many people playing the game right now that do not have facebook accounts. That will always be possible. For people to invite their friends, we do require facebook; but we also invite lots of people who just sign up on our site to be a tester, no facebook involved.
Again, in the future there will be more invite options; for now we've only implemented player invites through facebook. We understand this can be frustrating, but as of now we are not suffering from a lack of testers, so we're not spending time building ways for people to join. But we will, promise!
