Based on advice received here, purchased GoodSync for the 4 computers (one desktop, three laptops) we own. Also figured out how to sync with external hard drive hooked up to the desktop using the home network features on Vista.
My question is, if I want to access files on this external drive away from home, how do I do that? I see that there are services that allow this (LogMeIn, FileZilla). Wondering if people here have suggestions? Preferably something idiot proof. Anything more than that I may crash the interwebs.
