 Thanks are due to the following individuals:

  - T.C. Zhao and Mark Overmars for creating the XForms Library
    GUI. It's ease of use helped concentrating more on the
    program parts doing the work rather those dealing with the
    appearance of the user interface.

  - Luca Maranzano <liuk@kirk.linux.it> for maintaining the
    Debian Linux binary distributions of xisp up until version 2.4.

  - I. Ioannou <roryt@hol.gr> for providing an alternative FTP site
    for the xisp distribution, for his very helpful feedback and
    suggestions on improving xisp, and for extensive beta testing.

  - Peter T. Breuer <ptb@it.uc3m.es> for his help in extensively
    testing xisp on a *very* loaded system and his contribution
    to the alternative pppd-PID search code.

  - Raphael Wegmann <wegmann@ophelia.tuwien.ac.at> for providing
    the first set of animated XPM icons and code that runs the
    animation, as well as contributing code for the ip-up/ip-down
    support.

  - Doron Shikmoni <P85025@VM.BIU.AC.IL> for suggesting and then
    spending quite a bit of time testing the call-back feature,
    as well as his ideas on improving the scripting capabilities
    of xisp.

  - Ximenes Zalteca <ximenes@netset.com> for maintaining the RPM
    source and binary packages of xisp up to and including version
    2.3p7, for use with the Red Hat Linux distribution (Ximenes has
    since stopped maintaining RPM releases of xisp, so please
    refrain from contacting him on this subject).

  - Dave Holland <dave@zenda.demon.co.uk> for his extensive beta
    testing of the I/O-driven call-back code, and his contribution
    of perl code for parsing the ipparam string.

  - Tillmann Steinbrecher <tst@gmx.de> for letting me use the code
    he developed for the pppcosts program, as well as the phone
    company information included therein.

  - Fabrice Bellet <Fabrice.Bellet@creatis.insa-lyon.fr> for his
    extensive modifications of the cost calculation code to cover the
    case of non-linear minimum charge times (in per-minute PTT charging
    schemes), as well as his valuable help (feedback and patches) while
    beta-testing the PTT editor and its associated cost calculation
    engine.

  - Martin Bialasinski <martinb@debian.org> for maintaining the Debian
    Linux binary distributions of xisp version 2.5 and later.

  - Johnny C. Lam <lamj@stat.cmu.edu> for porting xisp to NetBSD and
    contributing his patches to the official distribution.

  - Takeshi Morishima <tm@planex-usa.com> for porting xisp to FreeBSD
    and contributing his patches to the official distribution.

  - Peter Denison <peterd@pnd-pc.demon.co.uk> for maintaining the
    RPM source and binary distributions for the Red Hat Linux
    distribution.

  - Andrew Bettison <andrewb@zip.com.au> for contributing bscanf.c as
    well as the code for passing xispdial's parameters via the process
    environment as opposed to using an environment file.
