Add a web part to NewForm.aspx or EditFrom.aspx

There are times when you may want to add a webpart to the new item form or the edit item form of a list.  Sometimes it may be to add code that will interact with the form or to simply add a message at the top of yoru form.  Whatever the reason, it isn't obvious how to do it.  
So go to your site and replace everything after the below depending on which form with: 

&PageView=Shared&ToolPaneView=2

EditForm.aspx

http://mycompany.com/MyCollection/MySite/Lists/MyList/EditForm.aspx?ID=213

NewForm.aspx

http://mycompany.com/MyCollection/MySite/Lists/MyList/NewForm.aspx?

DispForm.aspx

http://mycompany.com/MyCollection/MySite/Lists/MyList/DispForm.aspx?ID=213
