there is no eta or anything of the sort, as parts of the website will have to be redesigned for az3, along with many other additions and improvements.
please wait a while until az3 hits, you're welcome to join tsukichat then!
Out of curiosity, would you be able to inform how long the website has been under maintenance?
the server has been in maintenance since the 28th of december (although project registrations haven't been possible since the unlink, for obvious reasons). so really not all that long, considering the weight of pmr and specifically az3.
Should I expect to wait till 2020?
i could have sworn someone replied to this but it was deleted
