The CADTutor site is completely independent and is not supported by sponsors. It relies upon site-generated income to keep it going. Currently, this is done in 2 ways; discrete adverts and donations from site users. Without these 2 income streams, the site would not be here because the cost of keeping it online is considerable.
I have always been of the opinion that the content on this site and the help provided by the forum and its members should be made available free of charge. However, some of us are more fortunate than others and could probably afford to make a small donation towards the cost of running the site. In a sense, you'd be subsidising the use of the site for those less able to pay. So, if you have found the site useful and have benefited from it, a small donation in recognition of this would be very welcome.
If you would like to make a donation, click the "Make a Donation" link at the top of this page, select the amount you would like to contribute from the drop-down list (or select "custom" to enter any value) and click the "Submit" button. You will then be taken to the PayPal website where you can complete the transaction.
