How many days did it take you to get that first member? I'm finding that people seem to be reluctant to join, even at a pretty low price.
My "plan B" is radical. If I don't see many members in the next month or two, I'm considering making the entire site free (and I've got 20 videos, 12 ebooks, a bunch of other materials, forum etc). All related to my expertise in my area which I am known for. I'm very confident it will grow to an authority niche site with all that original material for free. At that point I'll turn it into an adsense site, as keywords in this niche are about $1.50 per click (though not exactly sure what I would get out of the deal).
My only concern is that I'm not sure if most people are opting out of the display network these days or not.
Anyway, I'm not giving up on the membership model yet, but I always need a "plan B" to stay calm.
Gaining paying members is not as easy as many people make it out to be.
