Nice job! it looks great!
Just two comments:
1. Guatemala is not in north america ;o) and central america is not listed in the users page (http://www.dotlrn.org/users/)
2. Can I use the very nice icons (http://www.dotlrn.org/product/) for representing the other dotLRN packages in the IMS-LD package? and if I can, where can I find them?
Regards
