The link from:

Under Skill changes to the forums posting regarding the reduced DC on traps links to something that existed on the old forums. I put "old_" in front of forums in the link and it works. The text in the posting is a bit out of date given the new setting as well.
I figure that any newbie might want to read that and wouldn't figure out to change the "forum" to "old_forum".
Thanks.
Link fixed, description is low priority.
