I recently joined the AC Cobra Enthusiasts Group on LinkedIn.

If you're active on the professional network LinkedIn, please join and feel free to send me a request to join my network.
It's a pretty small group right now (only 100+ right now), but it's a good way to expand your professional network and connect with people with similar interests. If you join, it takes the group owner about a week to respond to new requests.
