Tel, the issue as regards to getting into the site is now fixed. It was only occuring in IE7 and as I virtually always use Firefox, I didn't pick up on it.
As regards to the 'unread posts' link, it is still been displayed on my computer in the following browsers: IE6, IE7, Firefox, Opera and Safari. If you are still having problems, take a screenshot of the page and e-mail it through to me.
The rugbyleague.org forum uses Invision Power Board and for some reason it does have an extremely unsual way of displaying messages under certain browsers (particularly IE7). I think there is a way to change this although its best to ask the Admins over at RL.org as I'm not that clued up on that system.
What I will say is that the various different browsers available create more headaches for me than anything!
