hi,
Is wiki the best platform currently [*hides from
Ward*]?
Is the software/configuration used by (I think) PLOS for a similar thing
available somewhere to build on?
as mentioned previously, Open Journal Systems is popular
http://pkp.sfu.ca/?q=ojs
PLOS bases on Ambra
http://www.ambraproject.org/ which looks decent,
too, but I've never used it.
OJS is quite decent in managing the review process, using templates,
etc. Not as decent as Manuscript Central, but open, and good enough.
Ambra may be even better, maybe somebody used to edit in both and can
comment.
But seriously, starting a journal is not so much about the engine, but
more about the community to drive it. It wouldn't be unprecedented to
start a journal by preparing 1-2 issues WITHOUT a system to process
submissions at all.
best,
dj
