Please, please take a moment to peruse all your boards, on all your systems. Everyone and their cute little puppy dog is complaining about the moderating screen that is popping up every time you post.
IT IS BLOODY ANNOYING. Not only is it stinking irritating, it does nothing to speed this site up - in fact it slows it down immensely. This morning it took ages and ages for the pages to load - and this was the ONLY site that it was occuring on.
If you want to speed up your server, remove this silly moderating pop-up and look into the vBulletin hack that compresses signatures - this will increase your server speed exponentially. I posted about it on the "Question" thread below.
I know you believed it was helping, and that we all "bellyache" about "change" but this isn't just about change and not getting used to it. It's about you advertising a service that we're just not getting, and people are becoming increasingly angry about it. We're not 3 year olds, that don't adjust to change well - we were used to reasonably fast load times and we're simply not seeing them anymore. It will lead to a drop-off in posting, unless that's the idea.
Please - get rid of that moderating pop-up. It does a disservice to your entire site.
