Flex Chat is an Open Source IRC client, which is written in C#. It is comfortable, easy to use and configure client, which is supporting VB, Perl, PHP, Tcl, C#, C++ scripts and XML database.
Basicly it'll have functions like X-fire and Steam but still it won't be a copy, or a remake of those platforms. Everyone will be able to personilze the platforms Client and Server side, by their client and gaming needs.
