I noticed in the profile for this user, it may happen often but be less obvious with more prolific posters. In this instance, she is listed as having started five topics, but when you choose the topics tab, only three are there. I’m curious as to why.
Pure speculation on my part, but …
If two of the five threads have been cornfielded then I’d expect ordinary folks like you or I to see just that: a count of 5 topics, but only 3 visible.
