H.M.
My thought process is what if that site closes. Sites close every single day. My husband is a website designer/upkeeper and if people stop getting "sponsors" (basicallly ad space sold) they can't afford to keep their site open and they stop paying for the servers, the domain name.. etc and walla it's gone forever. So considering I see websites disapear every single day I wouldn't do something online. How can you guarentee that it will be there in 18 years? You can't.
Geocities for that matter just shut down. Who would have thought that. Sure you could download everything image wise before it did but the rest is lost.
So I really like the idea of just using a microsoft word document like someone else said. That is what I'm doing. Because I can back that up to my hearts content and there is never a worry.
