There have been Ads for years, if you haven't logged into the forum they show up. They should hide when you log in.
I just tested and this is true for me. If they are showing for others whilst logged in please let me know.
Current look is a temporary thing. The copyright info was missing from the OzRS forum theme, and the forum software owners were making threats so it was bought back asap.
You'll notice that the domain name has been moved over, now that the above was sorted.
There's a couple of things left on my to do list.
My aim is finished at end of August, I'm currently only getting the most important things done since I have a broken wrist in a cast so computer time is a bit difficult.
There are know bugs, someone posted about in the Website Feedback section, with IE.
There is a switch in the top left corner of the text edit box that changes from html mode to text mode, have you tried that?
