We do not have a regular income, because we do not really need it. Our expenses are limited to web-hosting. All work is done by a number of volunteers around the world.

We may get some income from advertisements, but this is limited and not a target.

In case you are worried: 6PC is non-profit, non-commercial, and has no aim to make money. We will NOT charge you for membership and NOT use the database to generate income.
