Firstly, the 'first' menu option will now work correctly. It's been working after a fashion but not correctly - this has now been fixed and clicking on 'First' should now give the correct answer for everybody - let me know if anybody still has issues with this.
Next up, reader comments. Previously the 'no let me edit it!' button relied on your browser caching the comment you entered and some changes we've made to stop some of the stupid internet caches from making the site outdated have caused some browsers not to cache the form contents either. I've just updated the add reader comment code to stop it needing that, so now it should work as you expect :)
Matt.
