OK, made a quick and dirty one that will get the job done. Can only work with what the posters write so it might become a mod job to create descriptive titles for posts in certain threads if that is what we want to do.
1. Go to the thread that want to index.
2. edit the actual thread address or copy and paste the address to another page
It has to be the main topic with the associated t=
to make it work. Can't do it from any other page.
The resulting text is BBcode to copy and paste as an index.
Anything without a title will just be blank and will show up as a blank line if it is just copy and pasted without deleting them. Wasn't sure if I should make a link for everything in case somebody wanted to add the text portion to the link or ignore any threads without a title. I opted to grab everything whether it had a title or not.
This can be used on ANY thread so it can maybe be useful for those creating worlds/settings as well as other places. After some feedback will make an official announcement.
