The Bugsquad is the Quality Assurance team for KDE. We keep track of bugs in KDE software and make sure that valid bugs are noticed by developers. You do not need any programming knowledge to be in the Bugsquad; in fact it is a great way to return something to the KDE community if you cannot program.
Read the triage guide and then to join us for one of our Bug Weekends. We meet in IRC in channel #kde-bugs on irc.freenode.org. You can get started have your questions answered there. Even outside of weekends someone in IRC will usually be able to help you.
