I have a PBEM (Play By E-Mail) pedigree. I have been writing in PBEM games since around 1998 or so... (Yeah, I'm old, sorry) In that world these things are known as JP's (joint posts) and are usually worked on off list and posted up when the two or more writers who are working on them are done with them.<br/><br/>I have been running a writing project on E that uses JP's a lot and most of them have been written in Google Documents (laterly google drive) which is really handy for collaborative writing and very easy to use.<br/><br/>PM's would work too of course, but Drive has a lot of options that PM's don't offer and would definitely merit consideration, though I would never advocate making it mandatory.<br/><br/>So if anyone wants a JP with Isi yell at me via PM. *Grins*<br/><br/><br/>M.
