This is the kind of thing that could go into the Wiki. However, I have heard that we will be seeing a quest database on the site in the near future and it could go there.
If you want to add things like this I would suggest using the quest name as the name of the Wiki page and placing [[Category:quests]] at the bottom of the write-up.
I was planning to start a quest timeline: Thestran Adventuring (timeline), similar to
http://www.vanguardspheres.com/wiki/...%28timeline%29. This would serve as an index into your write-ups.
