I want to join Tim in saying that you really must use the Design Rule 
Checker.  Eagle won't actually "allow you to make a connection" that 
isn't in the schematic.  But, it will allow you to add a trace, which 
is a different thing.  Connections are "air-wires" that you remove by 
routing traces.  If you add a feature (such as a trace) directly, Eagle 
assumes you know what you're doing.  Use the DRC to have it check that 
the board will come out right.

Unlike Tim, however, I have never found a problem at the last minute 
with the DRC.  That's because I run it over and over again as I work up 
the design.  You might consider this also as it avoids having a whole 
bunch of stuff to deal with at the end.
