OK, here's another question - about the "Ignore" feature. According to the vBulletin

[PhotoHokieNC]

Actually it doesn't work that way, if "that way" is the total invisibility apparently achievable in that vBulletin link. Not to beat the dead horse of "previous boards format", but a poster selected for ignoring does not disappear completely, just that poster's post content.

Or, more likely, I misunderstood what that manual said.
