How can I change the default group?

[DiscoBiscuit]

I am about to do something horrible and need to know if it's possible to change the default group from 'user' to something else.
Using SVN

The default group ('user') is actually from garry's code here: http://luabin.foszor.com/code/lua/includes/extensions/player_auth.lua#102

Hi,
I would like to change the default user group that people get assigned to when joining the server, while playing.

It would be helpful, for example when we decide to roleplay,
using an rp_user group that can not spawn anything.
Normally I would have to change everyone and all new joinging players manually.
But if I could change the default group ingame,
players would spawn in the rp_user group that I want them to be in.

Is that possible with a command or with a simple script?
PS: It would also be cool, if I could regulary change the group, but for multiple or all players at once.
So I wont have to do ulx adduser twenty times.

Thank you!

This is still something you would change in Garry's code or write a script to set the group in a high priority hook.
