Thanks to Sly161 for bringing this up.
Currently, the Criticism Policy is linked on the topbar, under "Info Pages". Since it's pretty relevant to anyone who wants to comment on mainlist pages, should it also be in the "New Member Info" box on the left-hand sidebar? As per discussion below, the idea has been raised of having policies be in an additional section of their own, not in the New Member Info box.
Granted, we haven't had an epidemic of bad crit (thankfully), but I feel like having the crit policy in a more visible place would help raise awareness of it.
