Somewhat OT, but what do I get access to if I sign up for Battlecorps? And what format is the stuff in.
Think of BattleCorps as a magazine, similar perhaps to the BattleTechnology of old. Once you subscribe, you get a bunch of "current" downloads, plus everything that is published during the period of your subscription. If you want back issues (i.e. fiction that was published earlier, when you weren't subscribing), you can purchase them via the BattleShop. Curiously, you need to be a current subscriber to be able to purchase old BattleCorps fiction. Which doesn't make a lot of sense to me.
BattleCorps publications come in PDF form. Mostly, anyways; a couple of items are published through the site's "News" section or through the previews and downloads forums.
The site does offer a number of free stories (The Heart of Dixie, Of Love and Peace and Cherry Trees Parts I + II, Art of the Deal among them), even if you're not a subscriber. Check these out to see the format the stories. Other types of publication include scenarios, unit digests, stable reports and ship profiles; there's also "interviews" but these were kinda thin on content.
Some people have been complaining recently about the amount of output, which has apparently decreased considerably compared to BattleCorps' earlier years.
Then again, I have to say the quality is much higher than any fanzine, MechForce publication, or even some BattleTechnology stuff. Every BattleCorps submission is thoroughly fact-checked for compliance with established Canon, and is fully canonical for the BattleTech universe. So while you get less content, the overall quality is higher (not counting occasional spelling issues, which I try to ignore but which, in all honesty, need to be mentioned).
