I recently noticed that no forum posts are showing up for me, just the title. I don't even know if this will show up. Is this an error on my end of things, or is it a subeta error?

This was a subeta error and should be fixed now. There is another board where they are discussing the slow loading time so if you are still having trouble loading, please post there. http://subeta.net/forums.php/read/793241/
