Dear Crunch Users, we had a significant spam problem in this wiki (resulting in more than 1500 spammer accounts and several 100 non-sense pages).

Apologies for the inconvenience! We largely regret to no longer be able to allow for open editing and adding of pages, but it seems this is the only way. Drop an email to Fridolin Wild if you need any help with that. IF YOU WANT A STUDIO ACCOUNT, fill in this form. Your CRUNCH team.

We are discussing several extensions:
