As far as I know there does not exist any feature, that if you own a pokerth server to make it known among the pokerth players.

Perhaps you could make an seprate category in here where everybody could post his server adress.

Or (what is much better) create a "master server" which recieves all adresses of servers that are online (so server musst send his adress to the master server at start up). Can be make very easy over the config.xml as far as I know (i am not a programmer )

If you start the game there must be a oppertunity to select the server you want to connect to

Think this would make the community grow much faster

I think I've seen preparations for server selection in the code. It might be just a placeholder dialog box now, though. It seems to refer to the geographic location of (other) servers.

Code here:
http://pokerth.svn.sourceforge.net/viewvc/pokerth/trunk/pokerth/src/gui/qt/serverlistdialog.ui?revision=1922&view=markup

I think it means that a solution that will allow people to connect to other servers easily is probably in the works, or that it will be at some point.
