Couple of Easy Questions, newbie here

I am using Merge Replication for my scenario (POS). I have made the publication (articles are a set of tables in DB ABC) and its subscription (in same DB and diff tables xyz1, xyz2). I have scheduled the push subscription as run continuously between Dates(e.g current date to 3 days ahead, just for testing). Now, Can I change this schedule? How can I edit/remove the artilce from the above publication?
ok i have found the solution for modifying the schedule here How to: Specify Synchronization Schedules (SQL Server Management Studio)
now i am searching for how can i edit publication(article(s))
