User-edited website (4)

I believe the answer is:

wiki

'user-edited website' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for wiki that I've seen before include "means to collaborate on a website" , "result of online co-operation" .)

I've seen this clue in the King Feature Syndicate, The Sunday Times, the Newsday.com and The Times.
