Analyze recurring webinar attendees

Using my Livestorm data, analyze who comes back to my webinars over the [LAST 6 MONTHS]. 1. Take my public webinars in that window. Skip internal meetings (all-hands, team syncs, trainings), one-to-one or sales calls, and test events, and sum up what you skipped by type in a line or two. 2. For each registered participant (not team members), count the sessions they attended live. Call people who attended 2 or more sessions regulars, and people who attended once first-timers. 3. Give me the share of attendees who are regulars, and how it changed month by month. 4. For each webinar, show how many first-timers it brought and how many of them came back to a later session. Rank the webinars that turned the most first-timers into regulars. 5. Show which topics regulars attend most (group the titles into a few themes). 6. Compare regulars and first-timers: average attendance rate, questions asked and chat messages per person. If the per-person chat counts are all zero, count each person's messages from the session's chat instead, matching each message to its author. 7. List the regulars who attended at least 2 sessions but none in the last 2 months. 8. Finally, draft a short personal invitation (under 100 words) to the next session of [WEBINAR NAME] (the earliest one that hasn't started yet) for the regulars who aren't registered yet, mentioning the webinars they came to. Don't send anything: I'll review it and send it myself. Answer with a one-line verdict first, then the tables, then one suggestion for the next webinar, then the invitation draft. If a number isn't available, write n/a instead of estimating.
