The second part is also a CRM issue. Recurring donations and fundraising goals are not a concern of the bylaws. The bylaws need to deal with membership/. What makes the single transaction necessary is the nightmares our current defintion is causing.
Let's say you give $5 in January, then again in March, and then $15 in May. In May you then become a BSM member because you have given. $25 in the last 12 months. But your membership does not expire in May the next year. It expires in January. Memberships are intended to be for a full year.
