EDIT 2013: Just to confirm, on Windows Vista/7/8 and etc you'll want to run in compatibility mode for Windows XP as well as run the program as an administrator, this seems to prevent a bug where data is sent incessantly
After a couple of days toying with SciDave's (awesome) network plugin, I made up this, a casual chat "mmo". You move around between rooms and can change your appearance while talking with other people in said rooms.
Thats pretty much it, so here are some images instead!

Multiple rooms to chat in!

Currently it only has two rooms, the spawn room and the "city". I'll hopefully make more in future. The server and client both use port 5000.
I haven't had time to toy with lag compensation, so it's likely that early versions will be laggy after many clients join.
Edit: [21/08/2011] Updated to version 0.2, here is a list of changes
-Update to new Network plugin version, smiley faces work in chat now :D
-Added a new command for the server
-Added client commands! Type /help to see them
-Added in-game admins, they can kick users in their current room from the server*
-Removed the HD textures, replaced with temporary pixel textures
-Kicked players do not leave their bodies behind anymore
*- including themselves and anyone else using the specified name
Edit: [20/09/2011] Well, I decided to release the source as I haven't been able to make a tutorial out of it yet. The source can be modified for whatever you want, as long as it's non commercial (as it uses the Attribution Non-commercial licence).
