I have tried to get access to the Wiki in order to add information on an English language Facebook group for Inkscape. It ask me to log in but I can find no way to get appropriate registration.

Can you help please?

Welcome to the forum!

It's my understanding that they had to shut down new registrations, due to too much spam. They must have some way of allowing new info to be added though. Maybe you can find some contact info. Or maybe someone here will know?

I think you can post on the mailing list to get someone to create you an account.

PM me with the username you'd like and email for the account, and I'll try set it up (not actually done this yet since we changed the settings)

Have added a note to the login page as well to give anyone else needing an account a pointer.
