In order of appearance at a typical meeting...

GREETER: arrives before the meeting and welcomes all members and guests as they enter. Explains to guests a brief overview of the meeting, and collects guest emails for follow-up. Being the greeter allows you to practice providing an outstanding first impression for potential new members.

SERGEANT-AT-ARMS: arrives before the meeting to ensure that the meeting space is ready and opens the meeting by introducing the chairperson. Being the sergeant-at-arms allows you to practice your organization and facilitation skills.

CHAIRPERSON: presides over the entire meeting, chooses the meeting theme, and introduces all speakers. Being the chairperson allows you to practice and develop facilitation, planning, organization and time management skills.

TIMER: monitors the timing of speeches, as well as the meeting as a whole, and provides a report at the end of the meeting. Being the timer helps yourself and others to condense thoughts and express ideas in a finite time limit.

GRAMMARIAN: monitors grammar, phrasing and proper word use, etc... throughout the meeting, introduces the "word of the day", and provides a report at the end of the meeting. Being the grammarian allows you to sharpen your listening skills.

AH-COUNTER: monitors the use and quantity of filler words (like, so, um, ah, etc...) in an effort to help speakers minimize use of them, and provides a report at the end of the meeting. Similar to the grammarian, being the ah-counter allows you to sharpen your listening skills.

VIDEO RECORDER: records speeches (with the speaker's consent) and sends the clips to each speaker as audio-visual feedback to help them improve. Being the video-recorder allows you to practice your organization and time management skills, as well as your ability to use recording technology.

SPEAKERS: give speeches they have prepared based on the current speech project path they are working to complete. Being a speaker allows you to develop competence and effectiveness in public speaking through mastery of speech organization, vocabulary, vocal variety, body language, using visual aids effectively, audience persuasion and audience inspiration, among many other great characteristics of excellent speakers.

SPEECH EVALUATORS: provide/present feedback on prepared speeches during the first half of the meeting. Being an evaluator allows you to develop both listening and observational skills. Evaluating other members' speeches is one of the powerful ways to become a poised and confident speaker yourself because it focuses your attention and awareness of what works and what doesn't in giving quality speeches.

TOASTMASTER: provides a 2-minute toast aligning with the meeting's theme. Being the toastmaster allows you to practice giving toasts (ya don't say!)

TABLE-TOPICS MASTER: presides over the Table Topics games (impromptu speeches) during the second half of the meeting. Being the table-topics master allows you to practice and develop facilitation and planning skills, while also enhancing your creative thought.

TABLE-TOPICS EVALUATOR: provides/presents feedback on Table Topics speeches during the second half of the meeting. Being the table-topics evaluator provides similar powerful skills as the speech evaluator, as it focuses your attention and awareness of what works and what doesn't in giving quality impromptu speeches.

GENERAL EVALUATOR: evaluates the performance of all the above roles at the end of the meeting and offers suggestions to all members to make the next meeting even better. Being the general evaluator allows you to gain advanced listening and observational skills.
