This is, of course, the menu selection you use to start a new event
You get to choose if you want to define all tournament options from "scratch" (i.e., you must enter all settings an information about the playing system and so on, yourself), or if you want to use one of the predefined tournament templates. If you choose one of the templates, many settings will be defined in advance: for example information on team/individual, groups, time controls, categories, ranking, pairing system etc. (You may also Define your own templates if you wish)
After you have entered the most imortant information about the event, (see Tournament options for help on the individual fields), click OK to confirm. You will be taken to the main window where you can start registering players, perform pairing, print reports etc.
