The screen layout on the android devices is slightly different than that of a desktop computer for the most part.
You should find an icon in the top right of the browser window with three horizontal white lines.
Clicking this should bring up a popup window labeled "Site Navigation for John-59597" with 9 icons and a large "More" button at the bottom - it is the "More" button that you need to click.
From there, there should be an additional 7 links (One greyed out likes)
From there just click on "Forums" that should get you where you hope to be.
