I have a site, which contains among other things an Issue Tracker – “Issue List” and a Discussion Board – “Issue Discussion”. What I need to do is when the user Creates a new Issue (when he does a “Save and Close” from NewForm.aspx) I need to automatically create a new Discussion thread. I can then go on to add custom properties to the Issue and Discussion and create a cross reference by passing the IDs. I want to know if the Schema.xml under C:\Program Files\Common Files\Microsoft Shared\web server extensions\60\TEMPLATE\1033\SPSSITES\LISTS\ISSUE can be manipulated to achieve this.

Conversely, how do I manipulate the same Schema.xml to add to the Standard toolbar an additional button “Discussion” and give it the functionality to add a discussion thread?
