I used to know about a site way back around 2010 time. I was a kid so yeah. I believe I made an account there but wouldn't know a password or username. The site had a white background and a blue logo. But i forgot the name. It looked the site had a sizable userbase. But I can't for the life of me remember its name.
The only site I can think of is Sploder, but that site had a black background with a blue logo, could they have had a white theme? I don't know, but maybe this will help. www.sploder.com/
