We're pretty much ready yes; the shell are essentially complete, I just need to update the textures.
What I think we really need before we can start the sign ups is:
1) A minimal set of 'rules' so people don't create anything
2) Some technical advices and guidelines so their shells can be integrated easily (naming conventions, export rules etc)
3) A summary of what Ahra Pahts and the shells are and why people should sign up.
4) An updated plan of the city
I am working on these right now and should be ready soon now, tomorrow or the day after tomorrow.
If anyone think of something else please advise.
BTW something I've had in mind for a while but repeatedly forgot to ask about:
Could we allow two (or more) people to sign up for side-by-side shells and form a larger shell for a big construction project? (provided shells are in same district) Some sort of 'neighbors association'.
Technically it doesn't change anything on our side.
