This message is no longer necessary. If people have further trouble with
this issue the solution is not to add 'helpful' text messages that
nobody will read, the solution is to take the multiple "things to do"
out of the helper and institute a "one screen, one thing to do" policy
for helpers.

First rule of the web: People don't read. (But they will happily take
the opportunity to blame you for not having help if you don't provide
it, even though they won't use it.)
