Hey again
Now then, instead of the old subscription scheme that you may be recalling the way it's done now is a "Moot Subscription" (see the drop down "Moot Features" menu across the top of the page). You pick your level (makes no difference) and you get for 1 year:
Access to the Moot Spire (a relatively underused but sometimes interesting forum) with the occasional playtest files (though it's been a while). It'd be a more valuable feature if Hunter were more active (and some of us hold out hope he will be).
A bigger Private Message box (50 total messages) which may or may not matter to you.
And... hmm, the store does not seem to be working
(EDIT: That may be a browser issue) So your main interest may be moot (sad pun intended). It used to be (iirc) a 10% discount on all items. So you'd have had to work out how much your savings would be to see if you'd be getting a bargain or if your membership would be more a donation in support of the site.
So, for now at least I'd say hold off on getting it unless you just want to make a donation. If you do, DO NOT pay for it with PayPal as that sets it up for automatic renewel. Use your credit card so it's a one shot deal.
I'd still have to advise holding off until Hunter gets things fixed around here.
In the meantime, if you want them, most if not all of the electronic media are available through DriveThruRPG
Hope that helps. Any more questions just fire away.
