Just changed my sig too. Also I've noticed that the sig for full members doesn't display properly on my mobile phone. It's not a huge problem though - just the bottom blue bar doesn't show up.
just updated my signature

, i have very low post counts in past months will any one confirm that all post counts will carry over to next month ?? and how to collect payment ??
Someone please correct me if I'm wrong but I think it carries over to the next month. You should be alright as long as your name is on the currently enrolled users list. So if you haven't reached the 50 post limit on the 17th of a particular month, then you can claim it on the 17th of the following month. If by then, you still haven't reached the limit, then you can wait however long it takes until you reach it and then claim it on the 17th of that month.
