The easiest way to get in touch with us is often via twitter through the @plaidctf handle. We will try to respond to direct messages as quickly as possible.
You can also email us at firstname.lastname@example.org. We will still try to be responsive, but may be slower responding to these.
We meet at CIC DEC 1201 most Fridays, at 5:00 pm (ET). We also have a mailing list that you can join to receive information about upcoming meetings. Be sure to use your Andrew email to subscribe.
