Hrmmm... might actually be possible given recent discoveries. I'll have to dork with this one
Would require a system similar to EQ2MAP. Users would need to submit quest titles and a URL (if one existed) to a website for inclusion in a downloaded DataSource.
The trick will be in discovering some hidden properties in the Journal (if they are available at all).
BTW, I knda had something like this in mind, which is why I linked it to the Journal in the first place
Might even be possible to cross-link EQ2MAP POIs!
