Is anyone having luck getting responses back from CEN via email? I am looking for a few questions to be answered, but don't really need the answers immedicately (say in 3 - 7 days response time) but I haven't heard back from them at all.

I don't have a problem calling but I am looking to see if this is going to be what to expect from them when it comes to support via email so I know that if I have some questions that don't require immediate answers, I may just pool them all together.
