Hi Cindy... Have you used the Auto Bio recently (since it was added to the WBE)? It's different, in many ways, from how it was before. There is a message found between the generated bio and the old bio explaining what to do next. Please see the WBE space page for more details. Also, two buttons, which I think are hard to miss, appear in the toolbar above the editor. One is 'Undo Auto Bio' in case you change your mind; the other is 'Delete old bio'. You don't need to turn these on. They always appear.
You mentioned the Needs Profiles Created maintenance categories. The good news (I hope) is that there is an option to add these automatically when there are people in census household members tables/lists who seem to be missing from the database. This is not a perfect system, but I hope it's useful. The Auto Bio can add location categories automatically, too, which can probably save some time.
A good thing about the new Auto Bio is that it has more options than before. The sibling list was actually optional in the BEE version, and it's the same now. This was something that was requested early on, not by a project but by a member who would always add sibling lists to their profiles. When you have a minute, please take a look at the options in the Auto Bio. (Click the extension icon to see the options window; go to Editing > Auto Bio > Show options.) If you see any option that seems odd, it was probably suggested or requested by someone who wanted it. And remember that they are options, that is, you can choose to use them or not.
