An index to subjects - I would assume that is what the Search function is for, you enter the subject and search for it. You can even streamline your search to just headings, everything, different sections etc
Numbered posts for reference - There is no guarantee that a post number within a thread stays that number so if you reference say Post #82, after deletions (moderation etc) that post may become #75 so it is not an actual reference any more.
There are several options for referencing specific posts:
1. Post in same thread - use the Quote button in the post
2. Post in another thread use the Permalink function i.e.
- Right click the date/time of the post and select "Copy Link"
- Paste the link in your post and you get:
3. I can get an addon that provides a Bookmark system that allows you to Bookmark any post/item on the site and puts it in a bookmark list for yourself, you can even set-up different Bookmark Categories, make them public for other users to see your Bookmarks or make them private. The addon costs $30USD and then $15USD every 6 months. I wonder how much use it would get i.e. cost/benefit. If a First Class member wanted it I would probably spend the money.
