I think those of us that can should subscribe at the $40 level not the $24 level. Plus if you have a business and can afford it, consider buying a banner ad at $45. Why not top it up to $100 ($40 subscription plus $45 ad plus $15 donation) if you can. Seriously. We need to keep this site alive.
Is a 'member' a subscriber, or is membership free? I see a lot of very active 'members'. Are they participating financially?
