First off I don't think there is anything wrong with calling people pledges, or using pledging as a verb...I hate when people say that it is demeaning. I used those terms and never felt degraded in any way...probably because I was proud of being a pledge and didn't have people telling me I should be offended.
Not to shoot down anyone's idea but I don't really think we need another forum. We do have people on here who are going through pledging but not tons, and if you have questions about how to improve your pledge program, etc that is covered in the Chapter Operations forum. Plus as we have seen, it may cause misunderstandings for NPHC members and even among NPC & NIC we can't decide what to call it.
Not to even mention once you get started discussing A it isn't far to B or C...some things, even if they are not ritual, should stay secret.
