That will be interesting and its a notable uncommonality but it should have worked anyway

OK I guess it was indeed the dot since I was able to log in with my account. Good catch!

Nice, Im looking into my code to see why that would fail validations, one of my libraries does email validating against lengthy lists of what are called "RFC"s which are the rules for internet standards published by internet governance committees out there in the world. Maybe the format breaks some kind of rule. I can code to fix it and allow it, since my email addresses merely exist to plug a hole for now in case they ever become relevant for non-chain accounts to login with or we decided to use them for things like notifications if the user wants to volunteer an address for such things.

@coininstant you found a bug on my side, confirmed. I just fixed my code to allow user names with the following patterns.

Now allows letters, digits, underscores, hyphens, and periods.

Previously period was not allowed in a user name using pretty default typical username validation libraries. I overrode them to allow it as noted above.

Should work fine for you now, on future attempts with your period-name
