November 2022


In This Month's Issue:


From the Executive Director

This week includes Giving Tuesday, a global day of giving, and I ask you to consider supporting the ASABE Foundation’s campaign to enhance the student competitions. Starting a few years back, the Foundation set the fundraising goal to equalize the prize money and support made available to each student competition. We have made great progress; however, we still need to raise more money to fully reach the goal. No gift is too small and you may give online, mail a check to Headquarters, or call in a donation.
Hopefully you saw Foundation President Lalit Verma’s Giving Tuesday message with the great news that contributions will be matched up to $50,000, thus doubling their impact. While we are encouraging giving to the student competitions, you are welcome to designate any Foundation fund or project of your choosing and still receive the match. If you make your donation online, be sure to click “+ If desired, designate a specific fund” if you give on-line and want to designate a specific fund or project. Additionally, there is a match available for those giving to the Young Professionals Community's 20th anniversary campaign, which is going on now.

Both the Foundation and ASABE are 501(c)(3) tax-exempt organizations, so contributions are fully tax deductible up to the extent of U.S. law.

Thank you for considering ASABE and the ASABE Foundation in your charitable giving.     

Darrin J. Drollinger
Executive Director

ASABE Engage


It's nearly time to bid farewell to Forums


With the recent launch of ASABE Engage, our new networking and collaboration platform, we will soon be closing Forums. Many ASABE groups have already received welcome messages through the new platform; please continue to watch for those emails as committees, communities, and other groups are transitioned to Engage. Efforts are also underway to transfer Important committee documents, like bylaws, to Engage, and that work will continue over coming weeks.

Set Up Your Engage Profile

Verifying that you will receive your Engage emails is a simple process—it likely won’t take much more time than it takes to watch our 90-second introductory video. Log in to, using your ASABE member credentials. You can then start setting up your profile and exploring.

One of the unique options available through Engage is being able to control the frequency for which you receive each committee’s messages.

Are You on a Standards Committee?

Forthcoming standards ballots will be distributed through Engage. Of those ballots initiated through Forums, only a few remain open, and these will be complete by the end of December.


We’re here to help! Contact for questions.

Students, Volunteers Sought for Interview Prep Sessions

The job-interview process can be stressful, but practice and good preparation can build the confidence and ease necessary for a candidate to make a great impression. That's why the Young Professionals Community and the International Student Branch are teaming up to host two events for undergraduate and graduate students, and they're encouraging other ASABE members to support the effort.

Mock Interviews—February 2
A mock-interview workshop, February 2, will give students the opportunity to practice and obtain feedback. ASABE professionals (non-students) are needed to serve as Interviewers. The workshop will begin at 6 pm eastern. 

Interview Dos and Don'ts—January 26
Prior to the workshop, YPC will host a webinar for students, ‘Interviewing: Dos and Don’ts.” This webinar will provide tips, insights, and best practices to consider as you polish your interviewing skills. The webinar is scheduled for 1 pm eastern. 

Questions? Contact Jonah Bolin or Becca Kallal.

Using DOI to Link to Journal Articles

The best way to link to content in our Technical Library is using the DOI. Take the DOI for the journal article or meeting paper and append it to "" to create the link. That link goes to the article abstract page that has links to the full text, citation, citation information, social media links, and other suggested articles. For example:
