I hope the projects and information snippets on this website are useful. Occasionally people send me a mail asking for a way how they can reciprocate. I don't take money, but I very much appreciate other forms of feedback. This page should give you a few ideas.
Let me know if you like (or not) my software and write me a note to <email@example.com>. If some of the code or information is useful to you, let other people know and mention it in your blog, tweet or pub. :-)
