You can't import a community into Dreamwidth, since by design, the vast majority of them contain the work of multiple people and one person cannot take ownership of that, even as a community maintainer.
I believe that if you open a support ticket there may be a way to import a community that's only one person's work, like if someone created a community rather than a separate personal journal to house their fic or icons or whatever.
