The other main screen in GIB is the convention card. We've tried to make it look roughly like an EBU convention card; you get to select a general approach and then fine tune it to your liking. GIB obviously can't know about every convention, but we've tried to give it a pretty healthy list.
The items on the convention card are of three main types. Some, such as the range of a 1NT overcall, are fixed. This is what GIB plays, and it doesn't know anything else.
Other options are checkboxes. Do you want to play Jacoby transfers? If so, make sure that box is checked.
Finally, you can give GIB an overall description of your system. Under ``General Approach,'' you can pick Standard American, 2/1 Game Force, Traditional, Standard with Gadgets, ACOL, or Kaplan-Sheinwold. Clicking on the small indicator tab next to the current selection will cause the list to appear. Then all you need to do is to move the mouse to your selection and click again. If you click the mouse in another region of the screen, you will leave the current choice intact.
When you're done with the convention card, you need to click on either ``OK'' to accept your changes, or ``cancel'' to ignore them. You can also click ``save'' to name your bidding system and add it to the overall list, or ``edit system list'' to remove some previously saved systems that you aren't interested in any more. You can't delete the factory systems.
