Hello and Welcome!

DotNetNuke is very much a meritocracy i.e. people who contribute get noticed and gradually over time become more involved in the project e.g. I started out by contributing bugfixes, then was invited onto the core team, then header up the security team and when DotNetNuke Corporation was started I was offerred a job (note: I'm not saying this is the way to get a job :) - just pointing out that there are a lot of employees who were well known community members - I guess from an employers point of view, people contributing work is a much better measure of ability/fit than a short interview)

As to how to start contributing (and getting noticed), there is a system called Community recognition which tracks some contributions -you can see them and their "points" at http://www.dotnetnuke.com/Community/Community-Recognition.aspx . Note everything is tracked at present, but it's a good way for us to see what's going on. In general most folks seem to start this way:

1. try helping answer questions either here or on the forums, or adding content on wiki.dotnetnuke.com

2. raise bugs/enhancements at support.dotnetnuke.com (we particuarly appreciate when the bug has a fix with it -theres a checkbox to indicate that)

3. create a module/skin - particuarly ones added in the forge - http://www.dotnetnuke.com/Resources/Video-Library/Viewer/VideoId/417/Developers-Introduction-To-The-DotNetNuke-Forge.aspx

BTW there is a "get involved" page at http://www.dotnetnuke.com/Community/Get-Involved.aspx which is helpful also.
