At present, seems to be mainly English (sic!) people on board but would people writing in other languages (presumably the system couldn't cope with other 'alphabets'?) be acceptable?
Obviously none of us speaks/reads all European languages but is there a way to use (e.g.) Babelfish on group? Are there other ways around such problems - translators in group, perhaps!
This won't be much of a worldwide group if non-English writers are excluded.
