These are in reference to the numbers in red in the image above:

1. If you are having issues with YInformer loading wrong, giving errors when trying to load or if you were directed by one of us to default YInformer, this his how and where.  On the Main Options tab, on the lower left corner you will see a Default button.  Clicking that will reset the YInformer registry settings stored on your pc and you will need to re-enter info like your bot ID and password.
2. You can view what Yahoo ID's have been logged in (or attempted) on your pc! Please note that this will show mistyped info as well.
3. Easily switch from enabling or disabling multiple instances of Yahoo Messenger.
