I would like to suggest one area in which an interested, passionate individual could contribute to the DotNetNuke project. Granted, it wouldn't be in a development capacity, or jumping directly in as the site webmaster, but it would be of great service nonetheless.
In past team chats, I know the topic of the DotNetNuke entry at Wikipedia was discussed. http://en.wikipedia.org/wiki/DotNetNuke Someone had mentioned that the entry was dated, lacking sources, or tagged.
One way to look at this is to say "Shouldn't the marketing team at DNN Corp. be handling the Wikipedia entry?"
Another is to say, "I'm a passionate DotNetNuke community member, with alot of knowledge, looking for my place to chip in. The Wikipedia entry is the second listed result in Google on a search for the term "DotNetNuke", and it would be of great benefit to the community to make that Wikipedia entry as complete as I can."
There are no barriers to updating listings in Wikipedia. While there are subtle things to learn about making updates to listings - what is acceptable info, what is neutral info, etc. - anybody can help contribute to the Wikipedia entry for DotNetNuke. The listing currently needs references added, and certain sections could be added or expanded (ie. architecture, modules, etc.)
The question will likely come up - why should resources be put into a Wikipedia entry, why not build our own wiki? Answer - even if we do tackle our own wiki, the Wikipedia entry will still remain highly visible and highly-trafficked - and important property for anyone searching for info on DotNetNuke.
So there's one suggestion.
