Driscoles, thanks! I have seen the Tanzanica site, and I do think it will provide a good starting place for LOTOW Africa.
NurgleHH, thank you for posting the Yahoo site. That one was new to me, and I plan to investigate it further.
My group, which is still in the formative stages, is interested in using the GW system for several different periods and genres, including but not limited to: French & Indian War (a la "Last of the Mohicans"), Scottish border reivers, the condottieri period in Italy, and also for general adventure gaming in the vein of "Indiana Jones" and "The Mummy (1999)". It seems like other groups have followed the same path!
