A simple way of compiling these articles into categories is to have a box like those to the left and right of this page, ie, Rigs Library, Beginners Page, etc. But you can only have so many of those before there is no room left for advertisers, etc. And it's the advertisers that help to fund the site.
The other way is to learn how to use the site to its full potential by using the search engine.
Try this:
In the search box above the features section type 'boilies' (you don't need the quotes). Then you'll be confronted with a million features (a lot anyway) that all have boilies mentioned in the text somewhere. Which is neither use nor ornament.
Now click on 'advanced search' and type boilies again, and click on 'title only' in the drop down box. Tick the coarse box and hit the enter key.
Try the same thing only with 'author' in the drop down box, and then you should have an idea how you can find anything you want quite easily.
The facility to find anything is there but so many visitors don't know how to use it.
