The show might be over but then so is TNG and people are still posting about that twenty years after it went off the air!
Yes, but this is also a Star Trek forum, so TNG conversation is bound to happen.
The LOST forum was closed when traffic there died down after the show went off the air. For some reason it just hasn't been deleted.
Start a LOST topic in the Sci-Fi/Fantasy forum if you want to talk about it. Nobody is stopping you.
