Us old guys need to be walked through any changes. I didn't like the loss of the tab either but I Do Like the way it is done now. Cool that you can select to read only unanswered posts or just new threads. By the way what is an activity feed, guess I could click on it and find out myself but like I said I'm an Old Guy and need to be shown what to do.
I read a couple of forums on an older format that I think inhibits the growth of those forums.
Good Job Guys, now that I am familiar with the changes they have improved the site and and make for a better experience
