I suspect I do not understand the mechanics of the Q&A system here - but it is puzzling just the same.
This morning I had 21 reputation and three bronze, while now I see 21 reputation and one bronze - and No questions asked - while I asked my first question on 11 or 12 January. (Actually I thought my reputation might have been 31, but very unsure now - not really something I am overly concerned about).
re: the bronze I am sure because at the bottom of my profile page it does say 21 reputation and 3 bronze.
Maybe the answer is "C'est la vie" :)
So, if you are able - please explain the mechanics. I suppose I could do a better search of the site - but you do not get reputation points for not asking it seems. And now I must also hope no negative points for asking a (potentially) duplicate question.
