In-game account management

[Holsje]

First of all, as said on IRC, really great work Russell. I had noticed the /account was available for admins earlier and it looks really useful.

And Specifer,

Thank you for your suggestion, trying to make administrating the server easier.

Could you pleaes open a speerate ticket / add a ticket on Github so we can discuss it there?
It would be nice if we could keep the posts related to the topic (accounts feature) so we don't lose track of all the suggestions.
