OK, I'll cut and paste (bold and italics mine):

What happens when my SONAR Membership ends?
Once you've paid for 12 months of Membership (either up-front or monthly), you own SONAR and all updates received during your Membership period. You can then choose one of the following:
a) Let your Membership lapse, and receive no further membership benefits.
b) Continue paying monthly. Membership auto-renews at the Renewal rate.
c) Pay up-front for 12 more months of Membership at the Renewal rate.
To me if I am a member for 18 months, then "during your Membership period" doesn't mean 12 months.
And again, if it did, everyone is going to drop out after month 12 until the next thing they desire comes out.
I think you guys are concluding something that they never said, because I certainly haven't seen it.
