How do you join groups on Facebook?

[:OO!!!]

How do I look at the different groups, and join ones I like?
Where do I go to look at groups I like?

just look at what groups your friends are in and click on them from there. on the right hand side you can click "join this group" but some are invitation only and some you have to be approved to get into.

there's a tool bar on the bottom of the screen. the most left says application. click it and click groups. then you can type whatever you like into the group search bar to find the group you want. To join, you go to group page and to the right under the picture, there's something that says join this group.

go to the group and on the right below the picture it says join group..
