Right now, I think this would be a little overwhelming for the
dictionary creators. Because we are so new at creating dictionaries, I
think just letting people add signs as they learn them is probably the
best bet - Maybe in a decade we can start weeding through existing
dictionaries and improving their entries...

Yes. Cool questions indeed! Give us all a decade...smile....;-)

I agree. It would be too confining right now, because only complete
freedom will help the writing system evolve into the writing system it
should be...for us to determine constraints, before we know them, would
hurt the writing system...People need to be able to compose documents
as they choose to write them right now...Maybe in a decade, we will be
able to do more...but even in English, I am typing this email without
some program pre-guessing what the spellings would be - yuk! I would
hate to have a machine finish my words for me - Val ;-)
