Hi @ToddZ! I made an initial commit to fix some of the issues you mentioned: FIX: Signup fields tab order and descriptions (#29772) · discourse/discourse@876591f · GitHub
Now, the tab order should be correct regardless of whether the full name required site setting is enabled or not. I also ensured that field descriptions are always shown, not just when the input is focused.
Our aim with the recent changes was to simplify the login experience. We removed the field descriptions that we felt added little value, but we also understand that customers may want to customize this. We are planning to add an option for site owners to include custom descriptions if they choose.
