I've been running mantis for ages, but never actually went through signing up to one, as I just administer one.

I just tried to sign up to this one, and got into a bit of trouble. I registered with my username, and then got the confirmation email which pointed me to a place to change my password.

I entered a password and then "Michiel" as my real name, as that's my name.

I got the error:

APPLICATION ERROR #807

The "Real Name" chosen matches another user's login name. Please choose another.

Please use the "Back" button in your web browser to return to the previous page. There you can correct whatever problems were identified in this error or select another action. You can also click an option from the menu bar to go directly to a new section.

So I clicked my Back button, and then I got the error:

--
APPLICATION ERROR #1901

The confirmation URL is invalid or has already been used. Please signup again.

Please use the "Back" button in your web browser to return to the previous page. There you can correct whatever problems were identified in this error or select another action. You can also click an option from the menu bar to go directly to a new section.

which meant I had to go to "forgot password" to get sent another URL to set my password,

Then I did the same making "MichielD" my real name, and whoops, I went through the above again, and so I eventually ended up doing it again, and then I put "Michiel is really my real name" as my real name, and it was accepted.

I'm glad I'm not called Bob.
