I should say so. By that rate, you should pass the million post mark in less than 2 weeks.

your only as big as your nitch is narrow. if your site is just general intrest, something that appeals to the masses, then i think you would need to have a lot more post and alot more active members to be considered big than a forum that is very specific in its target audiance, which is much smaller to begin with wouldnt need to have as many post or active users to be considered big. its all relative.

I agree. It's a more accurate way of measuring 'real' volume of activity.

Not necessarily. You may have lots of visitors and lots of downloads but little registration or posting, yet require powerful servers due to the traffic.

Someone has to be posting everything that the visitors are reading and downloading.

I have far more visitors than members...it's not unusual for them to lurk for awhile while they await a diagnosis (it's a medical board).

Once they're diagnosed, THEN they join. But their 'activity' is real, imo.

I don't think a board's size should only be measured in registered members. It's just one part of the equation.

I don't think it's a very good measure either. There are so many factors that play into how much hardware you need. Is search turned on? Do you allow downloads? Do your users tend to post more or read more? How optimized is are your servers? You could have 2 boards with the same number of visitors but one could require double the hardware.

Lots of different ways to measure "large" and "big."

Big-Boards has my forum ranked as the 10th largest post-to-member ratio, and we have just over 1.04M posts.

Is it big? Yes. Will it keep growing? Absolutely. I want it to be much larger, though. I want to get more lurkers active. Until then, I'm not considering it "large."
