I used it, (Happy Hour) and kept 7 of my free posts aside, but then found out that they were taken away by some counter during Happy Hour with out any warning so at the end of happy hour I was sad to see that I had no posts left for the day and was actually showing Minus 7 posts left for the day
I think iHub should change this system ....as a matter of fact why do you take away a post from my free ones for even posting here for an answer?
