If you have the navigation bar set for your journal then when you are looking at your reading page there should be a drop down menu of filters with Journals only, Communities only, and syndicated feeds.

If you don't have the navigation bar turned on, then add:

?show=P for Journals
?show=C for communities
?show=F for feeds

to the end of the web address.

If that doesn't work try adding &filter=0

like so: ?show=P&filter=0
