File transfers eh?!?!Umm use ICQ, sure... it's fine... I've transferd nearly whole CD's of info over it and it's o.k...
For slightly more reliable service, theres all kinds of FTP server software that you can get free off the net to allow you to assign part of you hard drive to behave like an FTP site... you can then allow people access to the files on that section and they can download, or if you allow, upload as well, so then you're swapping instead of just suppling... And you won't have to keep going back to MyDocsOnline to refresh yer stock...
Another option is Napster... a really small download, fairly quick and reliable transfers... But you'd have to co-ordinate yer online times with the people you wanted to transfer with where as MyDocs, they can access when you online or not...
Yer options are plenty
Try 'em all, lemme know which one you like best!!{~`
