Fizzer will you do anything about maxing out of invite list?
I mean, he kinda did just do that :P Now the tournaments will at least start. The feature you suggest is also a bit messy. Say I invite my friend, but he don't accept in time and now I have to re-invite him? Really, the issue is spamming of Forward Invites. Something like, only allowed to invite players who has logged in the last 30 days would help a lot too.
If you mean past tournaments that have already been created but are stuck, IDK what Fizzer will do with them. But.... if they are more then 100 days old, they could be deleted in line with the abonded games rule we have. (if you ask me ;)
