What groups to add a new user to?

I installed VidaLinux last night so I could try out a Gentoo clone and somehow durring the initial install it didn't take the user account I created so I went into root and created a user but didn't add to any groups.

Then I wanted to play with it and emerge world. Well it won't let me 'su'. It asks for the password but then tells me denied even though I immediately logged out and back into root with that same password. Then I looked at the user account again and noticed a few dozen different groups it could be added to and thought that could be the problem.

Which groups is a user added to durring the installation? Any group I should be a part of?

see if there is a "wheel" group ---> ie

Code:

grep wheel /etc/group

if there is add your user acct to it and then try to "su"

It worked, thanks, I also added myself to games and another group or two. Is there anywhere that explains the differences between all the groups?
