A good site/reference for needs and wants for a CMS or open source project? This is tricky when you first get started because you haven't had enough experience

A good site/reference for needs and wants for a CMS or open source project? This is tricky when you first get started because you haven't had enough experience to know the pain points and missing parts of the CMS. Once you get a bit of experience, you will know what is really needed but missing. Here are some other tips though. Find highly popular add-ons which are horribly outdated. Wordpress has a list of add-ons and shows the ratings, numbers of downloads and other information. If the plugin is way outdated (perhaps doesn't even work with the latest version of Wordpress) then you might have a good candidate for something to recreate and keep maintained. Alternatively you could find add-ons which are working with the newest versions and perhaps even somewhat recent but appear abandoned. Look for hugely useful and popular add-ons or features for one CMS which has no equivalent in another CMS. In some cases the feature / add-on might only be feasible for a certain CMS but in other cases this could signify a need. Check through feature request areas of the forums. If someone is requesting a feature which could be added via a third party plugin, then you might have a candidate. If there are 100 "me too" replies to the thread, then get to work!
