I don't believe the "no reviving old threads" rule should be abolished. Some threads don't deserve to be revived, and should stay "dead" rather than be revived. If we remove that rule, we could see a whole lot of confused members seeing threads by members who no longer post here. Though, I do think the rule is silly, it's there for a reason. However, some threads can be revived, but rarely are threads allowed to stay open if revived.
