OK, thanks for your replies. You are right MrYum, site loads for me - but very slow. I already contacted my host. Damn, why does something like this have to happen when I just submitted a site for approval, goddamn it
As for the resolution... I knew I forgot something. As you probably realised I mostly use tables on the site, they were 800px in width. Just corrected them, now they are 750px wide, looks fine at 800x600 now.
I also replaced the Iframe ad with a geo targeted banner. If iframe ads (like from adultfriendfinder, and so on) are a reason for an instant decline, this should be mentioned in the rules, imo... or I'm blind again as always if it's already there
Thanks for you help Greenie & MrYum!!!!!
