Hi, Learn how to: - choose an issue to fix from the Pharo issue tracking - create and send a slice with your fix - add entries into the World Menu Code must be sent as a SLICE named SLICE-Issue-xxxx-description. Patrick Barroca and Stéphane Ducasse have added a +Slice button in Pharo 1.1 to ensure this convention. For more informations on the contribution process, read "How to contribute" on Pharo wiki. Here I show how issue #2582 (Rearrange WorldMenu) has been fixed, based on WorldMenu registration chapter in the Pharo CollaborActive book.
