There is unfortunately no way to cause automatic cross-posting (of either top posts or comments) from Dreamwidth to LiveJournal for a community, like one might do for a personal journal. The best we can do is enqueue another import or two, until people stop posting here and start posting exclusively over there.
Ron, I think I can do better: I think I have everything I need* to set up a system such that when somebody posts to the DW comm, a post is automatically made here to LJ saying "User: USERNAME posted: TITLE OF POST on Dreamwidth, come join us there." with the title a link to the DW post. You could then restrict posting here to just the account doing the cross-posting (I would set up a new LJ account just for the purpose.)
I just can't do it right now due to being utterly hosed.
[* If somebody wanted to come up with a perl script that takes the body of a DW tracking notification email as an input on STDIN, and returns the URL of the post as a string, that would be the one thing I don't have immediately to hand and would shorten my development cycle by however long it would take me to write that. ]
