If you access the site on your phone by going to the usual URL (www.pnwmas.org) you wil automatically get the mobile version of the site - which is specifically formatted to work on portable devices.
There is a third party app that you may have heard people discuss called tapatalk that allows you to aggregate and interface with multiple forums so if you use reef2reef as well as PNWMAS you might want to explore that option. It isn't necessary, however, and as a third party app. can have issues when the main site updates. This happened recently and a lot of people couldn't log into PNWMAS using tapatalk for a while.
As for proper place to post regarding site issues I don't think anyone has defined one as of yet. If it is something that requires immediate attention then contacting the admins is appropriate. For more general questions I think they will typically get noticed regardless of where they end up but out of bounds seems fine. It is worth considering creating a place for this though - I'm sure some discussion will follow.
Hope that helps.
