Two little comments:
I just tried to reply “LOL” to a post and I got a message saying “body unclear. is this a complete sentence.” I clicked OK, but nothing happened. I wasn’t allowed to leave my comment without making changes. I don’t know if this is similar tot he 5-character minimum thing I saw before.
Second: on some very long threads, like the one that’s now over 1,200 replies, sometimes I want to make a comment that’s not a direct reply to anything recent. The only way to just reply to the OP is to scroll back for about 2 minutes. Is there a way to make it easier to “go to top?”
