If you think my projects are useful, you may want to contribute in some way, and you are very welcome to. Here is a list of what you could do to help the development of my projects, it's just a suggestion and you may well come up with your own ideas. The items on the list may apply to some projects only (for example to opensource ones only, as in the case of source patches).
I prefer contribution in the form of work, but if you wish to help with money donation, you are welcome to use the following link. Any donation, even very small, is greatly appreciated.
Very welcome are digital coin donations with bitcoin as well:
