You can delete only your own subtitles - i.e. the subs you uploaded while logged in.I know how I can upload but I can't figure out how I can delete.
So, how to???
Use the link "Correct subtitles", go a bit down the form, mark the delete checkbox and give a reason in the text box.
If the subtitle is uploaded anonymously or if it is a subtitle uploaded by another user, you can do the same thing, but then it is just a request and an admin has to approve it first.
