adding new person not on listal

The easiest way is just to find a link of them from somewhere else on the net (IMDb, Wikipedia, Bellazon, etc. most stuff should work) and then paste the link into the search field at the top of Listal. Do a search for it and then it will bring up the page for adding something new, if the link you entered hasn't already been used (which if it's a new person, it probably hasn't).

On the page it leads you to, just select "People" from the categories, select an image (I usually select "No Suitable Image" because I want to add better quality pics once the profile is made) and then put the person's name in "Name of Item." The "Item description" is optional.
