Wow, I had no idea upvotes worked like that. I knew about not voting more than about 20 times per day (which I'm still working on because I keep seeing what I think is good stuff), but had no idea about the before/after 15 and 30 minutes. I'm bookmarking this post for sure.
you are welcome
I am brand new to this as of today, have barely a clue but thankful for the info!!
