Just wondering how many of you are familiar with
www.yousendit.com?
As Gmail seems to be a popular choice among the users, yousendit.com allows for file transfers of up to 1GB!!!! yes, 1GB. I find endless ways to abuse this privilage, and since yousendit is a storage server (holding files for 7 days) it is a great way to share files of any sort.
It is directly linked to gmail some how, i find when i use other email addresses in the
to field they don't go through.. so i usually send the link to my own gmail (if the recipient doesn't have an account) and forward the link that way.
