Dr. Bob,
Assuming you plan to continue to use these sites (and the posts contained on them) for research purposes, wouldn't introducing a membership fee at this point introduce a major confounding variable? (or would it be a threat to validity? I've been out of school too long!) It would be nearly impossible to compare results from before and after the fee was introduced (aside from tracking specific posters who participated both before and after) and it would limit your population more than it already is (i.e. from "people who post on internet websites" to "people who are willing to pay to post")Just a thought.
