Problems with users who register
Hello, I have various problems with users who register for the first time.
1. Many use spaces in their user names, which means that they can no longer access the forum.
2. If I correct the name, their password manager overwrites it (my guess), which most of them have no idea they have.
3. Deleting and logging in again sometimes doesn't help either.
What can I do? For example, is there a way to force users to choose only one word as their user name when registering?
I use version 2021.012
Many thanks, Antje
