Doing the right thing, because it is the right thing (versus being forced by admins, or whatever), speaks well about your character, at least IMO.
No need to apologize. And we all occasionally forget to choose/change a category or whatever. But the effort to attempt to do something that benefits the group, is appreciated.
On the other hand, your attacks on a poster here, send a completely different impression about your character. Wouldn't be fair for me to not note that observation also. Conflicting impressions. JMHO. (No offense intended.)
