Why can't I login? It is most likely you have caps lock on or you typed in your password/username wrong, if you tried this a few times and you know it isn't caps lock or you typed your password/username in wrong then you probably forgot your password, so just simply click "forgot password" on the bottom, and the rest is pretty easy!
How do I join a group? Just simply click "view information" on the group you want to join and then next to where it says "group information" should be a button where you can either join or request to join a group, if you haven't been accepted into the group and it's been awhile, then the owner probably declined your request. But to be for sure you should message the owner and ask!
