Donation Information

If you find this software to be useful to you, please consider making a donation according to your means to help me continue to put in long hours, supporting and developing the software.

Some software developers call this coffee money in that, a donation of about 5 GBP is about the same as buying me a couple of cups of coffee. I think that this method is much better than requiring a user to buy a licence in order to have all of the features of the software. Whatever you decide to do, I hope that you enjoy using the software in whatever operating system you prefer.
