There's an old addon that I used to use that hasn't been supported since TBC.
If possible, I'd like to see someone bring back the addon 'Gag'. Better yet, if they could redo it from scratch for better stability and features, That'd be awesome!
The addon used to be able to play sound clips for people who had the same packs. If anyone is interested in working on this, as a former user of the addon, I could offer some advice on features. Message me if you like!
The project's marked as abandoned though. Also, wouldn't it be possible to create something simliar from scratch, using only original code, and a unique name for the project? I may be a bit new to the legalities of these things.
Also, what's to be done if the previous owner can't be contacted at all?
