Albus:
Of course anyone can edit Wiki stuff, minus the few protected pages. This has never changed from the Wiki's creation.
GMs *can* edit other GMs posts, but most of us are also restricted by the 10 image limit. This is why the Custom Gear threads, etc on the forums are out of date. If we try to edit them, it'll want us to remove most of the images, rather than add any.
This is we love referring to the Wiki. That, and it has a search bar. I love search bars.
As for the thread, I don't believe that thread has been updated because I don't believe it's still supposed to be there?
I'll have to confirm, but from age old, intern memory, I believe it was an attempt of Ayu's to move all the custom info over to the Wiki, as a workaround of that 10 image limit, but was shut down halfway, and the threads were to remain as the basis, while the Wiki was linked via homepage and lots of our signatures.
So yeah, will have to confirm if that's even supposed to still exist/have existed.
I choose you, Ayu!
At the moment, at the very least, it works as an entrance point, and have I mentioned how much I love search bars?
