  21 /* Wishlist for helpserv.c
  22  * - Make HelpServ send unassigned request count to helpers as they join the
  23  *   channel
  24  * - FAQ responses
  25  * - Get cmd_statsreport to sort by time and show requests closed
  26  * - .. then make statsreport show weighted combination of time and requests closed :)
  27  * - Something for users to use a subset of commands... like closing their
  28  *   own request(s), viewing what they've sent so far, and finding their
  29  *   helper's nick.
  30  * - It would be nice to have some variable expansions for the custom
  31  *   request open/close/etc messages. ${request/id}, etc
  32  * - Allow manipulation of the persist types on a per-request basis... so
  33  *   if it's normally set to close requests after a user quits, but there
  34  *   is a long-term issue, then that single request can remain
  35  * - Bot suspension
