I propose that MMORPG.com create a Voluntary Editor Review Board. What this board would do is read articles a few days before publish and offer up grammatical/spelling/factual errors.
Get 10 or so members who can are reasonably articulate, then create a special, private forum for them. 48 hours before publish deadline the author creates a post and plain texts his/her article. The members of V.E.R.B. who have the time within that span then review the article and offer suggestions within the guidelines listed above (i.e., not aesthetic ).
I think this would reap pretty fast rewards for the site here. Minor spelling errors stand a better chance of being caught, factual errors might not see the embarrasing light of day. In the long run, better product and higher volunteer staff retention since they won't get pummeled by the unwashed masses.
I volunteer to serve on this board.
