As I understand, following are criteria on which moderators for wiki award you points:
Action
Points can be awarded for the action
Min - Max
Added link
1 - 2
Corrected spelling and formatting
1 - 5
Added sentence(s) or paragraph(s)
1 - 10
Created new page with content
10 - 20
Restructured
1 - 20
Is there any way by which you are awarded more than the maximum points one can be awarded for the action for the wiki contribution, apart from what mention above.
Regards
JP
