Use this plugin to create a new post type called "Tip" with the following taxonomies: "skill", "topic"
This plugin was written to better organize content and leverage registered post types along with custom taxonomies. What this plugin will do is add a new post type called "Tip" along with a "skill" and "topic" taxonomy whioh are registered to our "Tip" post type.
The TipType supports the following: - title - comments - editor* - thumbanil
*IMO -- It's recommeneded that you use the editor "lightly", if you're making a really lengthy "tip", one with several pragraphs and screenshots it probally should be an post or "article" or "tutorial".
Our taxonomies are like "tags" (not hierarchical) it's best practice to keep these short and concise. Again, this plugin was written to better organize our "post", so good terms for the "skill" taxonomy would be: "easy", "medium", "hard" and NOT "guru", "super easy", "super crazy easy", but really you can use what ever you want (just hopefully you'll find a use for it).
