Registration Code follow-up question

Just wanted to say that I used the new plugin for registering the 200+ members of our homeowners association and it worked perfectly. It’s a simple, easy-to-manage way of ensuring that only members of a group are able to register. I generated random codes with > 8×10^17 possible values and used Word’s mail merge feature to print a custom letter for each owner.

Even older, non-computer-savvy owners said registering was easy.

Thanks for your help.
