I would agree with that as a general principle, but unfortunately, one of the key problems some people have had (not myself, except a little) was navigating around and finding threads they wanted to find in the first place… and the chances that people are going to be immediately subscribing to the ‘correct’ place in the first week of the new site is low. So (speaking personally) I’d consider the opening days of the board & opening threads a special case.
A solution might be to automatically include a ‘tracked’ category of "Needing help/giving feedback’ for all new accounts & any accounts yet to contribute. I’ll suggest it to the admins.
