You can watch it by just going to the link but you can't contribute to the conversation.
You sign up to twitter, find whether or not 1D are going to do a twitcam, if they are doing it, go to the link (or find it on twitcam) and watch it!
You can't do this.
Generally it helps if you are signed up to twitter as its easier to see when the One Direction boys are doing twit cams and when they do one you have to be signed in to twitter if you want to comment/chat on it, but basically you see when they are doing a twitcam and select the link they post on their twitter to watch them :)
You can go to the URL of the twit-cam and watch without having Twitter. However, you won't be able to chat without a Twitter account.
Just watch their twitter (@onedirection) they always announce it before they go live.
You Can't
You can get a Twitter Universe account to chat about wrestling free but the events to watch are pay per view.
