Allow a Bundle Member to Renew, Not Just the Bundle Administrator
In our club, couples are full members. There is no concept of a primary member. The ONLY reason we use bundles and give the couple two logins is because WA doesn't permit two fully independent email addresses. (There are 453 votes for that. Please finish the job.)
In the meantime, we have members trying to renew and emailing us because the Bundle Member is trying to do it, and you don't let them. (We try to tell them to log in as the Bundle Administrator, but the email macro for that doesn't work.)
Please let the Bundle Member renew. If some organizations have a reason not to do it that way, make it a configurable option for the organization.
