Hello Neo,
Yes, I do have 3 to 4 thoughts as follows but thinking of logic of them as of now.
1- On THANKS per post ratio, lets say 1 person is getting every 1.1 post 1 THANKS so as per that ratio badges.
2- On continuously logging days in forums one(not sure if we are keeping some information save in tables here?).
3- Monthly top thanks getting people badges(here also we need to save information somewhere, you could please let me know if we are saving this somewhere in forums?).
May be more to come
Thanks,
R. Singh
