hi avbravo
I just installed your plugin and got an unhandled exception after closing the options screen.

Steps:
1. installed
2. a message box appeared
3. the options screen with the GChat tab selected opened
4. look at the fields
5. press ok
At this point the main IDE showed a Red Icon in the status bar: Unexpected Exception - java.lang.NullPointerException

If you open the options > GChat again the message doesn't appear anymore.
Test Env Details: NB 7.0.1 Win7 64 bit JDK 1.7

Aristides, do you plan to fully translate the plugin into English anytime soon? There are still many Spanish words left here and there.

Your plugin made me deactivate my IDE, in the start say me deactivate editor and other components.
