At the moment there exist two fbsplash-related mailing lists: fbsplash-users and fbsplash-devel.
This is a list for people involved in the development of fbsplash. Send your posts there if you want to help with the coding, documentation, porting to other distros or if you think you encountered a bug.
This is a list for all users of fbsplash. Post there if your issue is related to fbsplash, but doesn't fall into the scope of fbsplash-devel.
