I suppose it wouldn't hurt to add in a few requests.
1) <PREVIEWPATH></PREVIEWPATH>
This would allow you to designate a path to all of your preview images/video files.
MxM could search for video files with the same file names as the directory of the game, and automatically add them. MxM could first search for WMV, then image files. Maybe even setup <PREVIEWPATH1> <PREVIEWPATH2> and so on for multiple directories (in case you have seperate directories for videos and still images).
This would be a quick and easy way to add preview files, but also a way to centralize their location.
2) Some sort of indication that a user is logged onto the FTP server, and possibly even an event interpeter, so MxM can tell you if the user is downloading, uploading, connected, or disconnected from the server. You could incorporate this into skins.
What do you think?
