Hi !
For now we just "reserved them", it takes 10236 G RC for one account at the moment (see the BeemPy Resource Costs Tool by @holger80 ).

For now, nobody can use them, as we did not put the account creation system in place on the website. But soon, these accounts will be available for people coming on our site and not already having a Steem account. That will allow them to create an account instantly instead of waiting for the 2 weeks queue when signing up via Steemit.

There will be no conditions to create an account through the website, but the delegation received on the created account (which is created with no SP at all, so not much RCs - just enough for 3 comments every 5 days) will depend on the usage of the app, and some metrics of the social networks linked to the account.
