/* Wishlist for mod-helpserv.c
 * - FAQ responses
 * - Get cmd_statsreport to sort by time and show requests closed
 * - .. then make statsreport show weighted combination of time and requests closed :)
 * - Allow manipulation of the persist types on a per-request basis... so
 *   if it's normally set to close requests after a user quits, but there
 *   is a long-term issue, then that single request can remain
