I've been using Boxstr.com for a while now, its a sick free site for hosting files, so you dont have to compress your edits on youtube and such. 10 gb monthly bandwith and 10gb of space. the max file size is 250 mb, which is pretty nice.

It will help me out, and hopefully you guys liek it.
PS: they only went down once, and it was soon after the site was produced. Because my files were acidentally deleted, they rewarded me with lots of extra space and such, so this company is very userfriendly.
