TC 2.09 Members, Liaisons, and Visitors,

 

I hope you are all having a great Spring and I look forward to seeing you all in Austin!!

 

Thank you to all the folks that have been a part of TC 2.09 over the last 20 years, and welcome to the new members and we encourage your involvement.  Please reach out to friends and colleagues and spread the word about T.C. 2.09 and let’s keep it growing!

 

We have a new in person meeting format with two Main meeting sessions.  We will use the first session (Monday June 29th 10:00am – 12:00pm EDT) to quickly review the subcommittee virtual meetings and address any open issues that require more attention. The second session (Monday June 29th 3:30pm – 5:30pm EDT) will be the standard format for the Main meeting where we will view the activities of the subcommittees and address any issues that require full committee review.

 

The virtual sub-committee meetings kick off the second week of June with the Handbook and Communications sub-committee meetings followed by the Standards, Programs, and GPC 37 meetings over the following weeks.

 

We look forward to your input and

we hope to see you in Austin.

Thank you for your participation and support!
