Thanks, it's good to see the forum is back up and running. I believe that was the longest outage there's been (or if not, one of very few) since I joined in 2017.
One small change I've noticed - and I say "change" because I haven't fully judged whether it matters enough to the forum experience to be an "issue" - previously, after clicking on a board, then back to the home page, the green arrow next to that board would turn gray, to represent that board having been viewed. Now, the arrow remains green even after clicking on and off a board several times. My guess would be that the arrow will still turn gray, but only after each individual thread in that board has been viewed, although I haven't tested this yet.
