I'm having some weird things happen too. First off, there is a message saying "Hello BlueCat it appears that you have not posted on our forums in several weeks, why not take a few moments to ask a question, help provide a solution or just engage in a conversation with another member in any one of our forums?" (I've been on vacation) and secondly, there are all kinds of underlined links within the posts. I see this sometimes when I check the site from work, since I don't automatically sign in there, but have never seen that at home. I always found those links annoying, but it wasn't really a problem since you can just log in and they went away. I'll be unhappy if they are a new part of the website even when you're logged in though.
