My chapter did the Alumnae ceremony for us. It was great and made us feel like "Official Alumnae." I couldn't imagine not having gone through it.
But, the collegiate chapter here does not do the ceremony. They wait until you join the local alum chapter. Then, the alum chapter does the ceremony.
If you have the opportunity, I would definitely recommend going though the ceremony!
Edited because I didn't spell "feel" correctly and I am a freak about spelling
