Alpha Gamma Delta allows her new members (the NPC doesn't call em pledges anymore) to wear letters prior to Initiation. They are not allowed to wear the Badge or the Crest.

There will always be the debate of whether the new members should be allowed vs. not allowed to wear letters before Initiation. I can see the good points on both sides, so I don't want to get into that debate. No sense beating a dead horse.

My issue is with the chapters who overlook their HQ's policy, and make and enforce their own rules.

If your HQ says NMs are allowed to wear letters, then wear them. If not, then don't let the NMs wear them. Simple.
