Special Welcome Message from Scott Burns

Welcome to the last two issues of the IAEG Connector for 2022. Our company that puts the newsletter together with IAEG gives its workers a two week holiday for the holiday season this time of the year so there will be no new news in this issue. The last two issues will look back at 2022 and see which articles our members downloaded the most, and they are ranked from 20-11 and then 10 to 1 in these last two issues! Everyone, enjoy this time of the year and have a super New Year! We will be back in January with lots of new news!
