I thought I was going to post a comment, but now I'm more interested in why I can't.
Yeah, me too. I emailed Grant about this over 6 hours ago. We'll have to wait until he fixes whatever is broke.
EDIT: Been close to 24 hours now and that thread is still locked down. Maybe Grant's on vacation? 🙂 What's weird is that, the way most forum software works, it takes an administrator or moderator to lock a thread. That doesn't just happen by itself.
The padlock icon is what tells us that thread has been locked, and like I said, that doesn't just happen by itself. It takes an administrator or a moderator with higher privileges than us to do that.
The binoculars icon means some forum member has elected to "watch" that thread. That means every time someone adds a new post, the "watcher" gets an email notification that there's been new activity in the thread.
The other icons are all about social media. Rarely use them myself. Just hover your cursor over them for more info.
EDIT: The thread in question is now unlocked. Thanks to whoever fixed that. I've been waiting to add a post there.
I wonder if the problem was in some way connected with the fact that, until I logged on, I was being told "welcome back" as "asusena armenia" on that thread, as "RobertB" on this one, and as "Heimhenge" on the topic list.
