Ah, a preset studio! Fantabulous! I prefer using Dropbox for all my uploading needs, but ye may also use Mediafire, Mega (although I 'ave no experience with it, there do seem to be a small population of users who use this site), and there are a few others, but my mind cannot recollect them at the time. Hope this helps ye.
If ye 'ave any other questions on le presets and what to upload, feel free to ask. I'd be happy to help!
