I’m using the API to delete a category and all related topics. Here is what I do:

- I get the category topic list
- I iterate over category topics and delete them
- I delete the empty category

The category “about” topic cannot be deleted. This is ok, because it is automatically removed when deleting the (almost) empty category. However, I would like to avoid trying to delete it when iterating over all topics (in order to avoid a server round-trip and an exception in my code). Is there a field I can check to see if a topic is an “about” topic?
