And another virtual season two can be found here...
http://www.firefly-tvs.com/guide.htm
This site starts with season two (instead of trying to complete season one first). The files are both .pdf and .pdb! They are written more like stories than scripts.
This one has 12 of 21 episodes for the virtual season two available. More to come, I assume. Originally, I think they planned one every two weeks. Don't know what their schedule is now.
I haven't read or listened to any of the stuff I'm listing here, but I am grabbing it all to consume when I find leisure time. Even if the quality is not high, I think I'll enjoy it.
We would all love to hear anyone's thoughts or reviews if you've read any of it. (Or am I the only Firefly fan here silly enough to pursue it?!)
