Get that warm, nice feeling of doing the right thing, giving my children food on their table, and so on? :-)
Anyway, even as this started out as a hobby,
I can surely admit that nowadays it is the registrations which keeps me going on...
You can send money to anyone, and PayPal charges it to your bank account or credit card.
It's faster, safer, and easier than mailing a check.
I would like an amount of 35 USD, forever, all eventual future upgrades included... :-)
If you're not sure this is really worth paying for, at least send my children a nice picture postcard from where you live?
