Here's an idea I have:

Make an IG book which is sold at either the book store or at the general marchants.

This book (it comes in various designs!) is scripted so that when you 'use' it for the first time, a dialogue script fires and allows you to insert a custom title/description. This occurs only ONCE.

The following 'uses' will just load the dialogue which displays the book title/description.

The idea behind this is so that people who keep IC journals on the forums have a hard copy to take care of IG as well and not assume all their secrets are safe. So basically once someone comes across your journal IG and uses it, they can head over to the forums and read the contents ICly.

Sure there might be some issues with the idea, but that's what I'm posting it here for. What say you?

We don't have a working SetDescription yet (we will soon hopefully).

I am working on improving the scribe system -- right now it's pretty rudimentary -- so this may well be one of the things I'll add. For now, you can use the in-game scribe to get something like this.
