Well i do some math and here is what i think.
for the Active badge i have:
(bronce) post a day for 10 days: x3
(silver) post a day for 25 days: x2
(gold) post a day for 50 days: x1
This means is not accumulative because i should have atleast 5 bronce medals because i have 1 gold.
so i.e: if you post 20 consecutive days you will have only 1 bronce medals, BUT, if you post for 10 consecutive days (stop one day) and then another 10 consecutive days you will have 2 bronce medals.
Im not saying this is good or bad, this is how it works.
so i think i need to stop enter and posting for a day for the "reset" and do it again if i want another gold medals .
