Dear Maria,

Sorry for a few days delay due to the holiday. 

Thank you for your enthusiastic response! I'm thrilled to hear that the idea 
resonates with you and your students. No worries about the timing; we can 
coordinate remote training sessions that align with your schedule.

I understand the time zone difference, and I'm flexible to adjust the lecture 
time to after 17:00 Greek time to ensure it's convenient for everyone. Please 
take your time to arrange the details, and feel free to seek advice regarding 
inviting other colleagues.


Looking forward to our future collaboration and providing insightful training 
for you and your students.

Best regards,

Yuan
