30 days from the date of the meeting is the requirement. Older reviews are welcome, but we cannot give the 6 weeks PA credit for those.
Go to the proper review forum for the type of session (Independent/Agency/Strip Club/etc) then look near the top left for the
button. Fill in the blanks in the template that pops up.
See this thread for much more info on review writing and what to put in those blanks;
