This article is for me a reminder. Don’t know why but I often forget where to go to for this task.
There are 3 places to perform this task:
1.In FrontPage -> File -> New -> More Pages Templates -> Web Part Pages -> Select the design you want and save to an appropriate DocLib.
2.From Portal Server -> Manage Content -> Create -> Web Pages Section, web Part Page.
3. From a WSS Site -> Documents and Lists -> Create -> Web Part Pages -> Again, save in the appropriate doclib.
I usually create a DocLib that do not appears on the left nav bar to store thoses pages.
