Why would you disallowed? I'm new here. Please explain

I was being silly/ridiculous. You typed to let you introduce yourself and I was playfully denying letting you do it, despite my having no power to do so, for the sake of being goofy.

Welcome. Great to have you round.

Man know I feel like a dork for crapping on the joke.

Feel good for having a joke and a funny misunderstanding too with a stranger.
