а как там заливать-то?
Ну так там рядом с кнопочкой "download" есть "upload". Вот ее и жмешь.
На всякий случай процитирую часть правил, касающуюся закачки:
01. All uploaded files must be in MP3 format. All audio files must be at least 128kbps. There is no upper limit.
02. Total uploads by any one member on the download page should not exceed 200 Mbs..
03. All uploads to Treble.Ru should be "TREBLE" related. If you are sharing a non-treble item, use an outside server such as Mediafire or Yousendit. Mixed boy/girl, boys & men, and young teen boys after voice change are considered Treble related.
04. All uploaded files must contain the appropriate file names (Artist, Album, and Track Titles).
05. The "Description Box" on the upload page should include Artist, Album name, number of tracks, bitrate of tracks, and name of ripping program if known.
06. If uploading a request on the download page, you should include the requesters name in the description.
07. If you are going to split large files before uploading, the accepted method is "WINRAR". If you do not have this program, ask for it on the message board, and someone will upload it for you.
08. DO NOT RESAMPLE files. If your files are 128kbps, do not resample them at a higher bitrate. This only wastes space, it doesn't make the files a better quality.
09. Only AVI, WMV, and MPG video files can be uploaded. Any other type of video files are not downloadable.
