Typo3 Newbie

Typo3 has a wonderful array of extensions from which to choose, and I love the extensibility of the CMS - however the documentation for some of them is very difficult to understand at first read.

For example - in the tt_news extension, in the Category Settings sheet (tab) of the plug-in is the variable “Max number of categorys texts” (with a “clarification” in the manual of “category-texts (titles)”!)

Now, what the hang does that mean? Does texts=words? Or strictly texts=titles? How many titles does a news article have?

Having absolutely no idea, I may have to wait until I put some news in, and see what comes out!
