Can't create account in Wiki?
 

When I tried just now, it says, "The action you have requested is limited to users in the group: Administrators."

They have to tightly control who puts stuff on the wiki.
For a while it was just getting spammed, the admins spent more time removing the junk and restoring the useful content than they did expanding and updating it.

What are you looking to update or add to?

This is an old thread, but I have the same question. I’m trying to add my vehicles data to the mpguino calibration page. It says, “action limited to group:users” but I’m unable to create an account on the wiki. It seems like creating an account is disabled.
