Eh, they were much easier to find on the old version since they were on the "Add new thread" page... Now I can easily check guidelines to my own stories, but haven't managed to find guidelines to stories that are not mine...
It's not the easiest thing to find. Whenever I find a thread I want to write off, or a story I want to read at a later date I bookmark it. If you look at your bookmarks you can check the story summary for the bookmarked story.
I always get to the guidelines by clicking the linked story title from the page where I'm reading the thread I want to follow up on.
So, for example, if you go to the intro page for my story In From The Snow, then click the linked words In From The Snow at the top of the reading frame, you get to the story summary page and can scroll down for the guidelines.
Of course if you added any formatting to the guidelines in Chyoo 1, it's all screwed up in Chyoo 2. And not in a nice way.
Guess I didn't notice that the guideline links had changed in Chyoo 2.
