I'm embarking on founding a charity and can use all the help and mentorship I can get. Still at the very beginning stages, it's called Internet Offline and we help let people who go from the Internet to the rest of the world know that you can bring big chunks of it with you. Tell your friends: Yes, YOU can have a copy of Wikipedia.
For my day job I write obscure software for library consortia with Index Data. Headquartered in Copenhagen it's one of the smallest multinational corporations with 14 of us in 5 countries. In the process I've gained many skills, most unusually a strong expertise in Mozilla tools---Firefox extensions and such.
