Cathy, I have worked successful with "First Class" at SFU centre for Distance Education, and I know that it is the software that york university uses with the WEIR - Writers in electronic Residence for the past two years - I also know that Composer in electronic Residence use it for sharing midi- compostions with students. Trevor owens at York university Faculty of Education has piloted this program for years.. First Class works on both MAC and IBM - and has both delayed cut and paste - and real time on-line chat response type capabilities. For example in one of the classes I did with a group of teachers - the assignment was to write a screen play -- one of our groups managed to get on-line and write the screen play copoperatively over a four hour period -- with different membfers asssigned to go off line edit, come back with feed back,, take bathroom breaks put kids to bed, and get coffee -- we ended up with a 'record tof the event" because Frist Class records and keeps all its histories - for all uses - not jsut the "manager" I could direct you to the Centre for continuing Education if you want more inormation - for me right now - it is more of a "black box" program - I can use it - and set up conferences -- but I don't know the nuts nad virtual bolts of it. cheers KathrynAlexander, Doctoral Candidate Simon Fraser University Faculty of Education., Burnaby, B.C.
