Suggested change in "last post viewed" functionality
A quirk in this function annoys me quite a bit. It's likely not a "malfunction" just a user cycle issue.
What I would suggest is to instead have it be a "first unread post" link instead of "last read post". The annoyance is when the last read post is the last post on a page... when you click the link to look at the new posts, instead you get the last page you viewed. I'm also not sure if it's my browser or what, but I also sometimes get no response when I use the drop down box to select the next page, and have to change the page number in the URL in the address bar to load the next page.
