With the proliferation of top-level domains we have had to update some of our old code that tried to make sure people were signing up with properly-specified emails.

In the old days, of “.com” and “.org” and other short domain extentsions, this was easy to check at the time someone entered an email address: if it wasn’t properly formatted we could alert the user right away so they didn’t go down a dead-end path.

We can’t do that anymore: new top-level domains are being launched on a regular basis by registry companies and the list of potential domain extensions is no longer finite or easily matched by regular expressions.

We thought we had done these updates a while back, but clearly something slipped through the cracks: people from “.software” domains were unable to sign up as new users.

That’s fixed now.
