I created a Network in WP3 and it works great!!! It's really powerful!
Now I'd like to have chance to post on 2, 3, or on all my community sites from the Post Create Page without have to copy the posts in each site.
Multipost MU plugin looks like it could give me this options but in the Post Create Page I can broadcast posts only to the main site: http://www.screencast.com/users/JuriT/folders/Jing/media/d8058889-30c9-4396-9031-12c7d3c6c132
I tried to post on the main site and it grabs the all the information except the THUMBNAIL (That's important in my case)
With ThreeWPBroadcast plugin I have the option to choose all my community sites, that's great: http://www.screencast.com/users/JuriT/folders/Jing/media/69860ffe-d45b-4a6e-a073-17aa05522a13
The problem is that it doesn't grab CUSTOM FIELD and THUMBNAIL!
Looking forward to having some help.
