I would recommend either the profile or a free space page. Using a free space page is generally a good idea for items that apply to multiple profiles.
See the profile improvement project for links to example profiles and steps toward improved profiles. https://www.wikitree.com/wiki/Project:Profile_Improvement
Sorry Ros, I disagree. Suggestion 801 "Big profile" does not kick in until the biography text contains 100,000 characters. That's a great deal more than 1,000 words. Even then it's just a warning, not an error.
Many excellent long profiles exist, way over 1,000 words. See this example and an earlier discussion about it.
