This tool allow you to extract group infomation.

this is what result you will get from it   [  admin | member | posts per day | posts per month | created date | group id ]

mainly this was use in multiple purpose such as  find big active group, find group that allow you to posts with out waiting admin group approve

first step of using this tool you need to have a list of group ID

you might get it from using Bulk group search by keywords 

if you like to wrok faster you can increase thread up to 200

but i would not recommand that

after tool successfully scanned , now you can export group infoamtion in to the text file

anyways for admin number  it's only work for forum (new Public Groups experience)

and also this tool have limit scan by facebook  if result showing nothing

that mean you get limit by facebook  you have to wait until facebook open it again
