I can't gain access to the forum through links in the email notifications either. Haven't been able to for a long time. I have to use the bookmarked links or enter another url in the browser

Rich, have you bookmarked or jotted down the urls that Geoff gave a couple of posts back? The tortuga one seems most likely to gain access, at least for me it's the one that works more often than not. I suggest you keep the urls he listed for future need to try if you haven't already
