Last month we got 150,000 hits, but only 1,840 visitors (a few of which were bots trawling the site).
But every single month the figures increase - it's definitely getting more popular.
At the moment it's using about 1.3Gb/month traffic-wise. If this gets up to about 50Gb/month then we'd have to think about actually paying for professional hosting. We're a long way off that though and I can't see it expanding that quickly - we're bit of a "special interests" group
(Oh yes, bit special sir!)
