You should try to have a member prepared as a back up in case things go wrong. It is recommended to present a speaker with a gift. Paper weight, pen, pin, letter opener, etc. ISSA will shortly announce the availability of these items from headquarters. You can also have networking sessions but members should know that there is no formal program.
Chapters usually have two kinds of meetings.
Chapter meetings are held for the membership and usually include a session oriented toward the professional development of the membership. Board meetings are also necessary to help the board run the organization. Board meetings are usually held in-between chapter meetings to facilitate planning for the next chapter meeting. Board meetings usually last one to two hours and are organized as small get-togethers to facilitate open discussion of issues related to the chapter. Minutes are kept for both meetings and chapters require varying degrees of adherence to Roberts Rules of Order.
