Resolved: I've upgraded the Kayak Forum to a new system.
I am currently experiencing technical issues with the KayakForum.com Bulletin Board system.
My service provider recently upgraded the operating system for the server KayakForum am hosted on. As a result, the forum software has some issues. For example you can't post messages, and I can't delete the spam posts you see. The fact that you can see anything there indicates that it is not totaly broken, but it functional inactive at this time.
My service provider seems to be indicating there is nothing I can do, but I'm investigating further.
