Jinn -
Thanks for the prompt reply.
You're right. I found the 'advanced search' option at the top of the stories page in the far right-hand corner, above the gray bar. However, it is not capitalized and sits beside a 'Search' box for Story Title/Author/Synopsis which I took it to mean that the Story Title/Author/Synopsis Search was the advanced search.
I wonder if others might have thought so too.
Having found the 'advanced search' (with your help), I tried it and found it excellent, allowing the search for (Yes) or avoidance of (No) different types of stories as classified by codes.
Well done. I know I'll find something interesting for tonight.
