Sorry for the late response. The mail server I used for the WWW mirror isn't working. If you want something to do right now to fix it, just make a new account on the rns.recipes web mirror and I'll delete your old account and you can use the new one you made
Don't worry I just found a solution :)
I created an account with all uppercase username, stuck a '.' in the email address, and voila, done. You don't have to do anything - all good! Thank you!
PS: this is proof the nomadnet version is better, it's just formatting can be tricky on the nomadnet :)
