Not doing any mining this summer.....bummer. But my reason for a forum dry spell absence was that I didn't realize I was logged out. So, every time I visited the forum it looked like no new posts.
I am kinda lazy and do not log out each time, so I don't notice many times when the forum logs me out, I just noticed this morning. But then again, it doesn't look like I missed much.
It's the same on my forums, about all I get to do is delete spammers to the tune of 50-60 per day.
