SourceForge openMSX mailing lists
These are hardly used anymore, so you will probably get a faster reply via one of the options above. If you're a regular user and want to discuss openMSX and possible problems, join our openmsx-user mailing list. If you want to address the openMSX developers directly, post a message to the openmsx-devel mailing list. An archive of old messages can also be found there.
