Probably the feature of Rseek that I use most often is the "Issues" tab which lists search results on help forums (many of which are hosted by the r-project). Here we'll introduce these and also discuss posting to the R mailing lists if you should need to. (Based on my experience this is somewhat unlikely - I almost always am able to find an answer to my question or a similar question in the forums). Please do note the requirements for posting to the mailing lists, or anywhere else (including Piazza), if you follow the posting guidelines carefully, you make it easy for people to help you.
