I'm planning to start designing free WordPress themes for .org but unless I missed it, is there any information regarding provision of support for my themes once they are listed? I read the guidelines for themes themselves, but could not find any info about how one provides support and if there are any specific terms or guidelines about support. For example, does theme support have to be done on the forums here or can I provide support from my website? Does support have to be free or can one create a paid support membership?
I would like to get all the facts before I begin free theme development :)
