  "EMchat is an Open Source project and we have had a lot of fun in
getting it into your hands.  But this project is NOT a \"for profit\"
organisation.  We do not receive any funding, Government grants, or
subsidies of any kind.  None of us who are involved with the project
are remunerated in any fashion for what we do with EMchat.  We are all
just volunteers, coding in our spare time.

Often the end user doesn't realise that their \"free\" software has
come at some considerable cost.  Costs and expenses like...

    Bandwidth and ISP expenses
    Hardware updates and maintenance expenses
    Hosting expenses
    Domain name registrations
    Electricity and other utility expenses
    Outrageous amounts of coffee for all-night coding sessions

If you have found this software useful/cool/entertaining please
consider dipping into your hard earned and making a donation.  Doing
so will give you the eternal gratitude and thanks from the EMchat
team, and think of the warm fuzzies you'll get.

Seriously, even if you decide against making a donation at this time,
I would like to sincerely thank you for at least taking the time to
consider it.  I hope you enjoy EMchat as much as we have enjoyed writing
it for you.

Steve Youngs
EMchat Project Lead.
