UserVoice is a very nice Web 2.0-ish web application, where users of different projects can speak their mind about projects in question. I like it for its clear interface, readability, and very low friction. Users can suggest improvements to projects, comment and vote on other suggestions. Project owners can give feedback to users, and official responses to suggestions. Some projects I use often like AnkhSvn, and StackOverflow use it as an official channel of feedback, and it seems to work very well.
I thought Castle Project could use that too, so few days ago I created a site for Castle Project. It’s not official (yet) but some committers registered there, and you can be sure they do listen to your feedback.
So if you do use Castle project, consider or plan to use it get involved. If you have a feature you would like to see in Castle, get involved. If you think something should be changed, have an idea for some improvements – get involved! As projects are approaching release dates (yes – they are, some will be released very soon), team is looking for ideas for next versions – let them hear you – get involved!
Oh, and if you want to get involved, the site is here.
