I've played with Plop, and it's very cool, but one of it's weaknesses is not taking edge support (or gluing) into account. I can't find some of the articles I...

Club rate subscriptions to Astronomy and Sky and Tel weren't (aren't) tied to Astronomical League membership. I think they both require a minimum of 5...
