1. If your LLC will be doing business (that is, holding itself out to the public) under a different name than its official name, you should probably file an assumed-name certificate in the appropriate office (which varies by state).

2. If you put a copyright notice on your Web pages (a mouseprint copyright notice is normally a good idea for evidentiary purposes, although technically not required under U.S. law), then the copyright notice should use the official name of the LLC, not the site URL.

Usual disclaimers: I'm a lawyer, but not YOUR lawyer, so this isn't legal advice, don't rely on it as such, don't disclose anything confidential in the comments (lest you waive any privilege that might apply), you and I aren't establishing an attorney-client relationship via this thread, etc., etc.

Ok, thanks a lot. In my example(www.newsite.com and my LLC is CoolCorp), what would be the correct wording? Something like: "NewSite © 2010 is an affiliate of CoolCorp LLC."?

The usual statutory copyright notice is "Copyright © [year of first publication] [Owner's name]"

In your hypothetical example -- assuming CoolCorp LLC was indeed the copyright owner -- a statutory copyright notice would be "Copyright © 2010 CoolCorp LLC"; there'd be no need to include the URL or name of the site.

I _have_ seen notices that say something like, "NewSite Copyright © 2010 CoolCorp LLC"; I'm not aware that adding the NewSite name like that would cause any problems.

Same disclaimers apply - I'm not your lawyer, etc.
