I am not sure that would work very well. I could easily take a screenshot, open it in Photoshop, and make is look like I was the 1000000th poster. ja ?
If anyone cared to notice, we are NOWHERE near 1000000 posts. We just surpassed _100000_ posts, not 1000000. (For those of you that can't count zeros, we just surpassed one hundred THOUSAND, not one million.)
