Notice of meeting need not be given to any member who submits a waiver of notice, in person or by proxy, whether before or after the meeting. Waiver of notice may be written or electronic. If written, the waiver must be executed by the member or the member's authorized officer, director, employee, or agent by signing such waiver or causing his or her signature to be affixed to such waiver by any reasonable means, including, but not limited to facsimile signature. If electronic, the transmission of the waiver must be sent by electronic mail and set forth, or be submitted with, information from which it can reasonably be determined that the transmission was authorized by the member. The attendance of any member at a meeting, in person or by proxy, without protesting prior to the conclusion of the meeting the lack of notice of such meeting, shall constitute a waiver of notice by him or her.
