I was on here for quite awhile last night,so no it wasn't down.
But i tried to reply to some threads and it wouldn't let me a couple of times but after refreshing the page it was fine and would allow me to reply to the threads.
I tried to get on the site Sat evening to post a link to some pictures of the Midwest Meet and it wasn't loading. It didn't say the site was unavailable just didn't load. I got the TB.com heading and the tabs at the top of the page but nothing else loaded. I gave up for the night.
