Just curious about something, hopefully someone can answer without me having to take up the support team's time with this.  And if this has been addressed elsewhere in the forums, feel free to link me to the thread(s).
 
I started my monthly Sonar membership in January. My account page says the next payment is due February 28th, which isn't a problem.  But then, the page also says "Membership valid through March 13, 2016".  I was under the impression that I can pay monthly for a year, but this makes me think it's only good until March? So I'm a little confused at this point.

It just means that if you don't keep up the payments, the membership will lapse on that date.
 
Another way to look at it, is that you get a couple of weeks' grace if you're late with a payment for any reason.

Cool. Thanks!
