And your recall would be right :)
Actually, the latest builds have a much fancier relationship
dialog, so you might want to upgrade to get all the relationshippy
goodness if you haven't already.
If you select two entities in the entity tree (outline view), you
can then click the "New Relationship" action and it will bring up
the New Relationship Dialog. I love the new versions of this
because it even has an option to add the foreign key attribute for
you, too, for non-many-to-many's (though I don't recall what it
does if you don't use Project Wonder -- it uses prototype 'id' when
you have Project Wonder).
In the dialog, you can select which sides (or both) of the
relationship are to-many, you can name the relationships, you can
optionally have it create a foreign key attribute for one-to-many
(single foreign key), or you can select the join attributes.

Hello,
I've been trying to work with Eclipse/WOProject for my latest
project, and it seems I can make it:)
But actually I'm stick on something which might be obvious:
creating a many to many relationship in Entity Modeler.
I used to have to select the 2 entities in EOModeler and do "join
in many to many", but I can't find where's that feature in Entity
Modeler...
I know I could create the join table, etc but I think I recall a
demo of EM at WWDC by Mike Schrag doing something like this...but
maybe I'm wrong.
Could someone tell me how to make a many to many using Entity
Modeler:)
Thanks
Xavier
