How to start your netplay session with MedClient

Press the "World" icon. It should end up red, indicating an online status. Check "Put Data to server". - If you have not set a Nickname previously for the Mednafen emulator, a popup will appear and request a Nick (an empy value will be changed to a default of "Idontwantanick"). (Optional) "Put Rom to server" will send a copy of your rom to external server, so that this rom will be available (temporarily) for download by people joining your sessions.. Don't pay attention to this. Double-click on a row in the grid to launch the Mednafen emulator and automatically connect to a server. Simultaneously, MedGuiR will send the game ROM to an external ftp server, specified in the appropriate FTP tab section (all data are stored crypted on the server). If the process was successful, a window like the one shown below appears.
In this row you can see all your Netplay sessions sent to the server This data is clearly visible by all users who use MedClient. Now, simply wait for an interested user to join your game session. When you close the MedClient window or when you close the Mednafen emulator, all your data (the session, and the ROM) will be deleted from the servers.
