Yes dear, of course.
But this is NOT NEEDED. 
I only did this because of some people ASKING me to do it. So, if they would like to buy a cup of coffee.
- telecomHall is FREE.
- And will always be FREE. Period.
- And it BELONGS to we all (we have a special group in Whatsapp → telecomHall Experts Group those people in that group are the real owners of telecomHall - an open-source platform).
So, there is no need for donation. Never! 
Anyway, if someone still want to “buy a coffee”, the donation will be reverted to FORUM.
Hope that is clear and thank you for being part of the amazing project.
