I am a pretty big flash guru, and I work on open sourced projects alot.
Well recently I just finished up a new File Hosting Module, it's free, and mainly created for other Flash devs to share and store files for forum use and what not.
I believe I posted this af few months ago but there have been many improvements since. some are...
shared Public folders
Anyway, it is free, and doesnt require any registration, so enjoy!
you can visit the forums to see other things as well
Have a look at the SHOWROOM area if you like to see some cool flash games and sites I made and some I am working on.
