1) click on Universes on the top left, next to ATLAS.
2) clck Add new Universe (on the bottom of that page).
3) Think of a Universe name. The name doesn't currently seem to be editable after creation, but the Summary and Description are.
4) Once you've created your Universe and opened its page, click on edit below ATLAS, and then add a Wiki (its name can be changed after creation).
5) After you've created it, go to the wiki's page, and click on either of Create New Document · Dictionary.
6) Begin recording!
Yeah... it's a bit clunky still. This is going to be replaced with a nice tidy language creation system. And a lot of features. Tonight, probably. Maybe tomorrow. I dunno. I didn't get much done last night, so I may fix the forum page number antics first.
