If you haven't logged in yet, you'll see a login box over on the left. If you have logged in, you'll no longer see that box. But you will see that your name is listed on the top left
This might not be so easy. This is what you need to do (assuming you are logged in, if you are not you can't log off): click the words "log off" next to your name on the top left.
I know this isn't going to be easy, but all you have to do is click on the links. If you get lost, look up by the beer, you'll see the drop down box, that'll get you to where you need to be.
First you can only vote for a caption once, you can vote for as many captions as you want, you just can't vote 20 times on one caption. So how is it that you vote. Again, we made this site rather hard, we are sorry for that. But all you have to do is click on the link that says: "Vote"
While reading an article, if you click on "Comments" that is located at the bottom left of the article, it will bring you to a text box. You can type your comment in that text box, can click enter.
At the bottom of where the captions are located, you'll see a box (if you have a login) type in that box, and hit enter. I know, I know... if you need more help, you can call CrashNet,and he'll mock you.
We really hope you don't need any.
