I love WA, but what's been driving me and our members a little batty is the lack of flexibility with regard to the event registration form and/or type. It's wonderful that our members can bring a guest, but when the guest that the member is bringing is another member who would receive member pricing, there isn't an option for that. An inelegant work-around is to create a different registration type, i.e., "2-member registration." This is clunky, to say the least, and a new field has to be created for the second member and his/her meal choice. That wouldn't be so bad, except that I can't make that field visible only to the "2-member registration" type -- it shows up for every type, which is really confusing, especially if you want to bring a guest.
What would be great is if under the guest option, there was a choice to say whether or not the guest was a member (and therefore get member pricing) or not (and get non-member pricing). If I was able to do that, I could have fewer registration types, and fewer opportunities for confusion and member complaints.
