How many do I get when I upgrade my account?

When you upgrade from a basic user account to "Artist", you'll receive 5 invite codes that you can distribute to other artists.

When your codes are used up and each marked as "Claimed" by a new artist, you'll receive 5 more codes.

When you upgrade from "Artist" to Patterned Pro, then you'll receive 10 new codes when your previous codes are all "Claimed".
