Alumni/Alumnae who don't know their place

[NotSoOldAlumna]

I graduated two years ago, and I still live in the town where my alma mater is located. I have been attending chapter business meetings on a regular basis (at least 3x a month) and the executive board has asked me to serve as an advisor this year pending a vote by the chapter at the next business meeting. I couldn't be more excited to continue serving this organization that has given me so much throughout my collegiate career.

That being said, this week was the first regular meeting of the semester and it presented a very uncomfortable situation. The outgoing president (we'll call her Jane) from last year is now an alumna, and she attended the meeting as well. The new president was doing a great job, came to pause a few times as she looked through the operations manual for some tricky voting situations, etc.

Every time the new president faltered, Jane piped in, whispering to her what she should be doing. Ok, I get that it can be hard to watch a meeting that isn't going well. When several members asked for status due to jobs though, it got really inappropriate.

President has never run a vote before, and Jane piped in, cutting off both the President and the Parliamentarian, running the vote herself. When it came time for discussion, Jane even spoke in favor/on behalf of several of the members asking for status. Per our bylaws, alumnae have no say in voting matters.

Jane went on to suspend parliamentary procedure for voting matters a few times, overruling our bylaws for the "convenience" of the chapter as some of the members asking for status were officers. I understand the need for having an e-board at the beginning of the semester, but it would be just as easy for the president to appoint an interim officer (allowed by our bylaws) until the elections in 2 weeks, instead of suspending procedure and hosting election the same evening.

I was uncomfortable the entire meeting. Since I'm not officially and advisor, I didn't feel that it was my place to say anything to Jane at the meeting. I know that it needs to be addressed, but the entire situation is complicated by the fact that Jane is my big.

Advice please on how to address this with her? Should I wait until I'm officially an advisor? Should I have a heart to heart with her before then, sister-to-sister?
