Suggestions

That is a good question. I think it depends. I have noticed with wikis that words are often linked at the beginning of each section, like you're thinking of doing and I agree that doing that makes sense due to the way wikis are often read, especially if it has been a while since the last time the word was used. However, sometimes I think the term, person or place only needs to be linked the first time it is used if it is not that central to the reader's understanding of the text (but has been provided with a link the first time it is used due to wiki convention). Hope that helps!

It does—for letting me bounce questions off you!
