Sorry for double posting but I messed up the last post. XD
I don't think its gonna work though....
I'm having a hard time understanding the whole thing.
When you submit your castle, click copy link to clipboard or just copy it. Then go to the message box and write the name of your castle,then highlight it and dont click anywhere else,just click the Link button above. Paste your link in the little box where it says: enter the URL and that's it! If you did everything correct it should look like this:
[url EQUALS YOUR LINK]NAME OF CASTLE[/url] (It's [url=YOUR LINK...I can't write the = sign because then the link will work XD)
It's just like SSTG said, I just wanted to show you a more detailed version. If you want to know anything else I'll be glad to help. I hope I helped. =)
