Every email goes out from GLAR, one per player, with their own name and personal link. The link needs no password.
A gig offer has the subject Gig offer: name, date. It says which chair you want them in and lists the band, date and downbeat, venue, address, venue phone, web site, dress, pay, setup and your notes. It is signed with your name and the band's name. Players answer by tapping the link. If they hit Reply instead, the reply comes to your email, so you can mark them in or out yourself.
Players also get an email when:
You get an email when a player turns a gig down, when they change back to yes, and when a poll closes. On Mondays you get a note about the week ahead if the band has gigs.
