Greetings.

This might seem like a strange or silly question to some, but I am truly curious.

I'm trying to set up a server, and documentation for the 2.0 branch of PEX is lacking.
Will the PEX nodes on this page work for the Sponge version of PEX2?

Since PEX 2.0 is still in development, the documentation isn't very complete yet.

The page you linked is for PEX 1.x, up to PEX 1.23.4 which works on 1.11.2 servers. Unless PEX 2.0+ has something you absolutely need on your server, you may want to consider using PEX 1.23.4 until 2.0 is ready.

I am trying to not sound demanding. I understand that other things take priority and this is likely just a hobby for zml does for no real pay.
Would a user-based wiki work to get documentation going for the 2.0 branch?

It doesn't look like I'm left with much of a choice. My preference is with 2.0, but since documentation is lacking I will have to use 1.23.4 until there's progress.

Just so I don't have to come ask later...
-Are all of the wiki pages for the 1.23.x branch?
-Does 1.23.4 support MySQL? (yes)
-Will I need to rebuild my database (I have the permissions from all of the other mods already on the database. I will backup the database before I switch regardless)

Edit:
I just noticed that you sent me to a bukkit link. Bukkit does not work on Sponge.

The Ore page has links to more documentation for PEX.
