Hi! Thank you for reaching out.
I honestly don’t know when will part 3 be done considering how big it is as a whole, but I know it will take at least a couple months.
As for part 4, it’s not in the works. I barely started part 3.
There are two different polls you can vote on if any of your suggestions fall under any of the poll options:

To get access to the discord server you just have to set up a discord account and associate it to your patreon account, then you will automatically be given access to the server :)
(I DO NOT give external invitations or links.)
