I don't know what is wrong with my empire thread, Seth was the last person to post something in my empire and that was back in March 29.
I think I have it figured out. I loaded your empire thread and it took quite a long time. I saw Seth's reply from March 29 and yours after his on April 1. The OP (your first post) is too long and contains too many links, pictures and special characters. In fact, your OP is so big that it takes up about 5/8ths of a web page all by itself. Compound that with the fact that it loads on every page and it's not allowing more than a few replies to exist. Any additional post with links or pictures can overload anyone's browser.
As I see it, you have two options.
The first will take a lot of patience on your part. You'll need to log in and open your empire thread. That'll take a long, long time so be patient. Edit your OP at first by just deleting everything and putting a single line of text in there. Once done, you should be able to go back and edit again and put what you want in there. Just be careful not to overload it again.
The second option is to abandon your old thread and create a new one without so many special characters and links.
It's your choice either way.
