Try changing the title of one of your knowledge tiddlers to not be in CamelCase (add some spaces to it, and/or change the capitalization).

• Notice the drop-down showing you any links that will break when you rename the tiddler.
• Visit the tiddlers those other links were contained in and update the links to match. You'll have to use the [[square bracket syntax]] now.
• What are some of the advantages and disadvantages of camel-case linking? If you have a TiddlyWiki use case in mind for yourself, do you think camel-case links will be a good idea there?

Note: If you rename tiddlers often, the Relink plugin can update the links automatically.
