Did a little detective work:
1) Wikipedia says 2011-12

2) They're still listed on the ECHL's future teams list and not on the links of current teams at the top of the ECHL website

3) The team's website doesn't look like it has been updated in a little over a year.
I'd say it looks like they're taking this year off as well.
