Good to hear from you Clement.
I'm not aware of any dedicated Map sites but a quick search came up with these tutorilas for Map 2000
There is also an "Inside Map" manual published by New Riders press.
Also a "Using AutoCAD Map" - http://www.amazon.co.uk/exec/obidos/...619372-2885225
Since you're now working with Map, perhaps you'd like to share your experiences with the Forum. If you're keen, maybe you'd like to moderate a Map board on the Forum. What do you think?
