I think I may have found the main cause of the lag which makes people double post, etc. The admins have done a great job in reducing the problem, but here is what I learned. The rotating ads displayed include some hosted at some place called oz.valueclick.com. I didn't notice until I switched from IE to Firefox because on IE the site simply does not load, but in Firefox it loads the site partially, then displays the current object path that is being loaded. Ever time I experience a lag it reads "oz.valueclick.com".
I hope this is the correct place to post this. Hope that helps.
