What makes you think the availability of Despecialized Editions on the forums.thestarwarstrilogy.com does not also use torrents or usenet (or something similar)?
As mentioned in the other thread on the Despecialized Editons in this part of the site:-
Some info & help for Harmy’s Despecialized Editions of the Original Trilogy… has a couple more options.
These two threads are worth looking through as well:-
Despecialized Editions by Harmy : Index of ‘How-To’s & Help’ Threads | Index of ‘General Despecialized Threads’ | ‘Where are they? And how do I get them?’ mega-merge thread…
‘How do I do this?’ on the OriginalTrilogy.com
