I dont get this. Dont you get to have 14 activity points if you post 14 times inside each period? I have posted 14 times sinde 02/09/2014, shouldn't I have added +14 to my activity?
No, you may have already gotten those 14 points prior to then (yet still in that period).
In other (longer) words:
DONT WORRY ABOUT YOUR ACTIVITY, it shows you aren't in the forum for posting relevant information or to have a discussion. Rather you are here for signature programs.. From now on in, please contribute and don't worry about your activity, you can provide relevant, constructive and useful information wether your a newbie with 14 activity or if your a legendary with 1200 activity. Plus time will fly by (so will your activity) if you post helpfully not spammy.

Well I do worry about activity, while I post normally. Also, signature campaing is the only way to get BTC unless you have enough FIAT to invest (99% of people dont). If we want BTC to succeed, we need more ways to get BTC, most people aren't going to put their FIAT into BTC because its too risky. For now signatures a good way to get a little BTC monthly, but we need more ways.
I still dont understand the activity thing anyway, i think i may be mentally retarded for these things. I cant understand the algorithms. Can anyone explain it in layman terms? I thought it was, 14 points in 14 posts inside these 14 day periods.
