It was slightly updated but it has the same content and the same accounts. If you had an account, it should still work.
There are plans to change the structure or use addons so we can have multiple versions of the same content for the different game versions (stable vs experimental).
Somehow I never ended up actually adding anything myself as wiki looks much scarrier on the inside without knowing wtf language its using etc… but definately a good start already for stuff to add if its not already, and to get others to help out.
with what?
The wiki? - The wiki was/is way out of date, especially with experimentals. One of the VERY FEW drawbacks for such a fast paced modding community.
