We now have inline comments and a not-very well sorted out Menu system.
Please report problems and experiment on this thread.
PS: As new etiquette for the nested comments, please resist the temptation to queue-jump threads by just replying to the first comment (except for this thread).
PPS: Some entertaining comment-gremlins turned up (instead of trolls).
Well, we had nested comments on this site for a few hours 🙁
