I provide support online in my own time in various places after working fulltime as a Senior Technical Consultant (Mainly for Java, Oracle and VB stuff) so I don’t have any financial problems and hence never think of actually accepting or asking for any payment for helping someone out as it actually makes me feel good helping people out and as corny as it sounds that is payment enough for me.
However I’m interested in finding out how many people do actually charge for such support? Like issues with a WordPress plugin or some layout fixes, that kind of thing.
