I'm pretty sure I was above 300 rep here, now I'm back at 200+. Yes, I'm small fish. Which means every point counts ;-)
Basically, I'm annoyed that there's some rep changes that are not logged, at all, all you get is... well, nothing. Just a thought "I'm sure I had more rep" or even a feeling (like when you were, as I was, a few days off the site) "I think I had more rep"
Why did my rep (if it did) decrease? Maybe there are means to see it, but those are (quite) certainly not available to me.
"If you log, log everything, or the log's useless." You can quote me on that.
