I poked around a bit in the code. This isn't a "wizard" like I was talking about, but it is possible to create an additional account with a specific account type. Here I've added a drop-down menu for selecting the Account Type when creating the additional account. And this drop-down, like the password box below it, only appears if you're already logged in and the server allows additional accounts:
Then you just select the account type from the drop-down:
And the new account is created with the correct account-type and page-flags in the database. Implementing this was actually really easy and only requires editing three files: two in the core and one in the Frio theme. I could also add a script to auto-select from the list if the link was like /register?type=32 which would be a "Public Group" (type 3, flag 2).Thoughts? Would this be enough to end user confusion over how to create a Page or a Group account?
