http://mobile.cougarguard.com works fine on my blackberry. I actually don't think you even need to be logged in (but you do have to allow cookies).
The only thing that doesn't work well on mobile.cougarguard.com is the New Posts (or any search for that matter). New Posts is basically just a search result and the search results page hasn't been modified yet to take advantage of the mobile style. Thus, it appears in regular Cougarguard style. It will still work on a mobile device but it will have more graphics and thus not be as lean. One of these days I'll get around to updating the search results page to take advantage of the mobile style.
