I know you're looking for either admins or contributors for this page and as a lover for Sorcery! and the whole Titannica Universe, I'd be more than happy to add in pages and information here and there. I know what it's like trying to find something about the games or lore and not being able to find it (damn Inkle and their creative adaptations haha).
I don't think admin would be good for me, I'm not on all of the time, but just permission to contribute?
While your politeness is appreciated, no permission is needed to make contributions! The wiki thrives on people who drop by and add things, so feel free to work on any article you want.
Admins do not necessarily have to be active (I'm not always!) but are just trustworthy people who have extra powers like editing the wiki design and banning/telling off wiki vandals. In light of that, if you're interesting in becoming an admin on the backburner just in case you want to do anything with those powers, let me know!
Check out your Admin Dashboard, which can be found by clicking "Admin" on the bottom toolbar. It has links to all your new tools. Please let me know if you have any questions, and good luck with your new (old) wiki!
