For what kind of things?
Could simply extract the stuff you need somewhere.
For example the commands; https://rochet2.github.io/downloads/TC commands.html
(for a local copy just download by right clicking and save as)
We removed it awhile back. The Commands list was probably the only good thing on the wiki anyway. We mainly removed it because we didn't need it since the whole point of the wiki was that Eluna documentation was on it. When Eluna moved to eluna.emudevs.com, we kept wiki.emudevs.com up for awhile and eventually removed it. Besides, you can practically find the commands everywhere. You can even view TC source to see the commands or just view Rochet's link. Whatever the case, commands list isn't uncommon.
