This brings up another matter regarding 'official timeline'. I kind of see each individual thread as an 'alternate' timeline but still fits in with the character and the setting overall.
For instance, let's say oh I don't know, one character does get injured in one thread and scars because of it later. I think it only applies to THAT thread though. At least for me it would I think. Other threads have their own timeline. Or if a character or his/her companions get killed in a thread, unless you want them to be out of the picture for good, I only see that as the end of the thread and not the actual character. True, the character (or companions) may be dead in that particular thread but elsewhere they may be alive and kicking, thriving, etc. Think of the idea of multiple alternate universes where different things could possibly happen. For one who has watched the science channel a lot the idea isn't that farfetched. They have talked about theories of that nature. And perhaps I am getting a bit off track here, but oh well.
Or is viewing it as alternate happenings the wrong way to go about it? Of course, others may choose to look at it differently and that's their choice.
