Hello fellow TextFugu users!

I’m relatively new to the site (this is in fact my first post to the forums) and in my usage of TextFugu I’ve come across some confusing information concerning kanji. As I was reviewing the kanji, some kanji, such as the kanji for “mouth” (http://www.textfugu.com/kanji/%E5%8F%A3/#top), provides confusing explanations on when the kun’yomi and on’yomi readings should be used. The vocabulary entry for “mouth” tells the reader that when the kanji character is by itself the kun’yomi reading is the reading that should be used but later on, in the vocabulary entry for “entrance”, the explanation states that the kun’yomi is used even though there is hiragana attached to the kanji.
I was further confused with the kanji for “evening” (http://www.textfugu.com/kanji/%E5%A4%95/#top) because it supports the statement that a kanji attached to hiragana employs the kun’yomi reading. I’m not quite sure if this is a mistake or if I’m simply missing something but if this could be set straight, I would greatly appreciate it! Thanks a ton in advance!
