It’s now possible to vouch for users in the signup process via IRC if you are connecting from Blinkenshell (Titan). The !vouch command has been modified to a more intuitive syntax:
The optional argument username specifies the username (signup username, not IRC nickname) that you want to vouch for.
This is a new feature and it has only been tested for a short while, please report any bugs to me!
And as always, do not vouch users right away. Let them proove to you that they have good intentions and that they are going to stick around before you vouch. I usually don’t vouch users the first day I see them on the chat, but wait until the next day to see if they return.
