For anybody looking for ways to contribute to Forena, here are a few examples to consider:

• Add a thumbs-up to any (or all?) of the forena videos that you like (and suggest more video topics as David requested).
• If you haven't done so, go ahead and download/review forena. The most recent forena version is probably a good bet. Even beta and/or dev versions have a reputation of always being quite stable. Create issues for any kind of glitches you may still find, or questions you cannot find the answer for in the available documentation, such as the tutorials that come with forena, and/or the community documentation.
• Share (contribute) any of your forena reports that you think may be valuable to others to use or learn from, in the format you prefer (descriptions of it, screenprints, or frx files). Pretty sure they'll be considered for potential inclusion in forena also. Checkout #2354903: New Sample report SVG Graph Demo for an example of that.
• Share what you think makes forena such a great module, e.g. in the format of real world use cases added somewhere in the community documentation. There's an issue for it: #2355193: Extend community docu.
• Spread the word about forena, e.g. by tweeting about it, blogging, liking, whatever fits for you.
• Do Forena presentations at Drupal Camps (why not ... Cons?), similar to what Dennis Povshedny did at DrupalCamp Kyiv 2013. Make sure to add a link to such presentations around here also. Thank you Dennis, great presentation! ... Any plans for an updated 7.x-4.x (or above) version soon?
