Seems like this answer should be so obvious. I apologize, because I tried to find it.
Since I got good answers to my question, I was trying to 'vote up' the person who gave me the good scoop. There is an arrow with the number '2' by his, and another persons, answer chain. If I mouse over the up arrow, it indicates I will be toggling that off. That seems wrong.
I was able to click the check mark, to indicate that this was a good answer.
But when I check my profile, it indicates I haven't voted for anybody. I want people who help to know they are appreciated.
Will be happy to follow a link that explains what I'm not seeing. I really do try to read the Gol Durned manual.
