This site is great! One thing I would suggest is something similar to SO where users are able to edit other user's posts. I believe this will be extremely helpful especially for newer users who are not as familiar with the typical format. I am not sure if this is something that will be available to users once they reach a certain trust level, as I am still at the "basic user" level. If its not, I believe this feature will allow the community to help moderate the site, and in turn reduce the workload on the RStudio team.
Thanks again for creating this site!
