Thread:User talk:CodeCat/Remove duplicates when there are multiple heads/reply (2)

What I'm asking you to do is to modify line 287 so that you copy 'heads' to a new array with duplicates removed before concatenating. This is easy to do. I would do this myself if I had permission to modify this file. Take a look at أنتليجنسيا and you'll see what I'm talking about.
