Hi there, Lorisa. I'm Lostris, a VSTF member who has been frequenting this wiki to help you stop the vandalism spree that has been hitting this wiki. It has come to my attention that a lot of the vandalism originates from IPs. Recently, it has become an option in Special:WikiFeatures for administrators to make the decision to disable anonymous editing on their wiki by enabling the feature "Require all contributors to log in". The choice is entirely up to you as an administrator, I just thought I'd let you know of the option. Kind regards.
No problem, it's what the VSTF is there for :-) I hope the disabling of anonymous editing will at least slow down the vandalism on this wiki, but if it doesn't, don't hesitate to ask for help if you desire it. Good luck with this wiki!
