Hi

I have an issue where I need to realistically just capture the email address of a user and then once they've entered, I need to let them on to the network. That all works fine.
Ideally, the user wouldn't have to ever put their email address in there again, they'd just be allowed on the network.

After a few thousand users join the network, I get issues where the pipes are still in place for previous users and it stops being able to allocate for new users.

Is there a clean way to do this?

Thanks
