However, if I could form an offline club, it might be a reading club; these are quite popular.  Mine would be a Books and Tapes Club.   This would allow people with dyslexia, or with visual problems, to join if they wanted to.  Now and then, ALL
members would listen to a tape.  We would then discuss, not only the book itself, but how well or poorly it was read.
Then again, I might start a Sunday Night Lunch Club for fans of
Maud Hart Lovelace's "Betsy-Tacy" series.  The  SNLC would meet on Sunday evenings, preferably if the next day was a holiday.  Members would take turns hosting.  Sandwiches and coffee would be served, and, if available, songs from the Betsy-Tacy books would be played and/or sung. 
Or I might form a club for making rosaries; members would also pray the rosary at each meeting.
I said (wrote) that I can't have an offline club.  What I should have said is that I can't have an offline club at this time.  Perhaps someday I will be able to have one.
