The OpSim project invites donations to our development fund. These funds are for instance used to keep the website up and running, but it also allows coders from the community to work on support issues or on sustained development toward specific roadmap objectives.
Once logged in at PayPal, funds may be directed to firstname.lastname@example.org
If you would like to see specific items being implemented with a higher priority this is possible by making a donation. Please contact me directly to determine the scope, timing and donation amount.
