The admin CGI is processing the mass subscribe/invite list. While it is
doing this it is not generating any output. If it takes 'too long' the
web server will time out waiting for output from the CGI. That's what's
happening here.

The amount of time is set by apache's TimeOut directive

You'd need a custom script to do the 'extra text'. I have added an
invite_members script I use at
<https://www.msapiro.net/scripts/invite_members> and
<https://fog.ccsf.edu/~msapiro/scripts/invite_members>. This can send
invitations including the 'extra text'.
