For now: the first big arc of the postboot continuity of the Legion of Super-Heroes/Legionnaires. It's fun, it has loads of cute characters, and there's an OT3. Download it. Watch this space for more uploads and explanation.
Third arc. Note that the LSH folder has a lot of other stuff in it. Those are crossovers. You should be able to tell when to read them, but if not, tag me.
Fifth arc. And as far as I'm concerned, that's where it ends, because after this, the writers of suck and fail and OOC take over.
