[Post a research note](/post) to solicit input, publish tests or prototypes, ask questions, or just to keep track of links and research documents. Posting is like making a blog post in that you get sole authorship credit and only you can edit your notes. <p><a class="btn btn-large btn-primary" href="/post">Post a Research note »</a></p> **[Wiki pages](/wiki)** hold our collective knowledge base. Wiki pages feature curated knowledge condensed from work documented on research notes. They can be edited by anyone with a publiclab.org account. **[The Archive](/archive)** hosts open data created by Public Lab tools for all to use. Currently featuring maps in visible and infrared, the archive will be expanding to hold spectral, water quality, and other types of data generated by Public Lab tools. <a class="btn btn-lg btn-default" href="/website-basics">Read more about how to use the website</a> **** ##Community structure * Organizers: http://publiclab.org/wiki/organizers * Staff: http://publiclab.org/wiki/plots-staff * Board: http://publiclab.org/wiki/board This diagram roughly shows how these groups are nested: ![diagram](https://i.publiclab.org/system/images/photos/000/002/655/large/organization_chart.png) Also, see the [glossary of terms](/wiki/glossary) used around Public Lab!
