So what's the point of potential activity? I believe even if you have 10,000 potential activity if you don't post anything after getting that amount of potential activity, your activity rating will not go up. Am I right?
That is right. Activity is calculated this way to show how old your account is and how active you were in 2 week periods (period for activity update)
1st two week period: 300 quality posts. The estimator assessed my account with 14 activity and 286 potential activity.
2nd two week period: I don't post anything.
Will my account
a. Remain 14 activity and 286 potential activity.
b. 28 activity and 272 potential activity/
C. 14 activity and lower potential activity.
I don't really get potential activity.
Potential activity means it is "potential". So you don't get anything extra if you post extra. Every 2 weeks you can only get 14 activity no matter how many posts you make as long as it is not 0.
e.g.
1st week: you make 300 posts : Activity= 14 P.Activity=0
or
1st week: you make 3 posts : Activity= 3 P.Activity=11
Value of potential activity
This is only for account farmers/traders. They buy these cheap spam the forum (risk getting banned) and then sell higher!
