It might be custom, written by theymos.
Can theymos set it up for my forum if I agree to pay him for his work?
I want him to set up the above mentioned features if he has time.
Anyways, thanks mprep for your significant help
If you have some programming knowledge I don't think it will be a big problem ... Try to go to Epochtalk (the new forum software) on Github , It should use the same algorithm as this forum since Activity feature will remain the same .
Will be testing out Epochtalk soon and check if it can fulfill my requirements out of the box as you said.
