You won´t have to worry about any government spying on you if you create a chat room in Chatcrypt.
With the whole spying drama, services where we can encrypt what we create and send is obviously becoming very popular. One of services is called Chatcrypt and getting started with the website is very simple. On the site you will find all the info you will need in order to really get to know the site. The site also offer webmaster to embed Chatcrypt in their own websites using an HTML embeded code.
If you want to create a chat room, just looks for the ENTER A CHAT ROOm part on the site, type in the name of the chat room, choose a username and then a password. Remember that if you want your friends to join in on the fun you will obviously need to give them the name and password of your newly created chatroom. Chatcrypt opens up the user created chat room in a separate window and it was an input field at the bottom for typing. Sorry, no file charing feature but hopefully if enough feed back is given they might add it in the near future. Let us know what you think of the site in the comments section.
