I'm using the action "Update User" to allow an already logged in user to "create a new site" on my multisite network. However, I've run in to a minor quirk: If I use the username as the Site address I get a validation error, "Sorry, that site is reserved!"
I created a quick screencast and uploaded the (unlisted) video here: https://www.youtube.com/watch?v=0tSO05qlAoY
Of course I can use any "Site Address" other than the username and it works fine. Has anyone run into this before? Thoughts?
How can I solve this conflict? Thanks!
