We have advanced from the basic text chatting that became popular during the rise of the internet, to webcam chats and audio chat rooms, that allow you to see and hear others on the site.
We also now have a user friendly mobile interface so you can chat with friends whenever you want, wherever you are!
There are categories such as 'solids' (where the digits repeat eight times), 'ladders' (12345678), 'radars' (01133110 - where the number reads the same left-to-right as right-to-left) and 'repeaters' (20012001 - the second half is the same as the first half).
Then there are 'radar repeaters' (12211221), 'super radars' (20000002 - all the internal digits are the same) and 'super repeaters' (where the first two digits are repeated four times, such as 63636363).
Others have fallen by the wayside, but we remain, and have grown to one of the most popular and user friendly sites on the internet.
