Couple of Forum quirks
I've tried using the message button / chat bubble on your profile page, but neither work on my phone via Chrome. Not sure if it works on the computer. That's why this is being posted.
Second point - when in the base Forum (list) view, I scroll down to see what is highlighted for new posts / replies. If one is present, the header for that section and the accompanying post are in bold. However, the header for "DIY Speakers" is in bold all the time. I know that it's just a small thing, but it catches me several times a day, on both phone and computer, mostly with Chrome, but sometimes with IE. Not sure if you've noticed.
Have a good night.
