no idea about sending files, never tried... I'd guess so?

As for storing the network, that's true and that's also why I just fixed the two functions above to automatically take care of it whenever possible. I'll update the doc to specify that in case of doubt, Network should be checked and "yahoo:" should be added in front of the email for future reference, if you want to be 100% absolutely sure you always refer to the proper contact.
