can someone who is in the "chatmail mutual help" and/or "DC explorers" Delta Chat groups get PM me so I can leave the groups and have you invite me? I don't know how to invite myself.

a couple weeks ago I made a new Delta Chat account and invited myself from my old one, but despite the invite appearing to work, I never got any messages, and now one of them I can't even send messages (the other the messages just seem to disappear into the void) @delta @maikel #DeltaChat

edit: got invites!
