What people have to understand is that the Rockbox forums have a very specific purpose: to provide support for Rockbox. When we restrict the content of posts here to Rockbox-related issues, we are not trying to be unhelpful. To the contrary, we do that so that we can be as helpful as possible with respect to Rockbox-related issues.
Between Llorean, myself, and some others, we read every post that is made in these forums, and we make our best effort to reply to posts that pose questions about Rockbox's use, development, etc. Off-topic posts impede our ability to provide the support that is the purpose of this forum. For example, I often read the Rockbox forums from my phone while taking the train to and from work. I know that Llorean does the same. It takes a very long time to get through the posts when there are many threads that have nothing whatsoever to do with Rockbox.
We have nothing against forums for general computing questions, questions about music management, or even just idle chatter. But there are plenty of those types of forums available on the internet. Just as you wouldn't go to a Dell forum to ask questions about your Apple Mac, we prefer that people not use the Rockbox forums to ask questions unrelated to Rockbox.
