Okay, that question I understand.
First, no, you can’t exactly protect your work by copyrighting a company name and “putting everything under that” – that may be what people appear to be doing, but, that’s not how it works. When anyone posts material to a website, what they have a copyright in is the actual material that is subject to the copyright. The poem, the play, the computer software, the song.
This copyright exists from the moment the work is “published”, by fixing in an acceptable medium (on paper, on tape, on a website, on a cd, in a letter, whatever – mostly it has to be not locked in your head. (So in that sense, your acquaintances who think they are “putting everything under the company’s name” (“Copyright 1999 Spelvin & Co.”) on their sites do have copyright protection, they are just misstating the reason for the protection)
If you desire, you can obtain additional protection for each separate work by REGISTERING the work with the U.S. Copyright Office. This costs 25 or 45 bucks per work (Can’t remember exact amount); the form is very straightforward. My husband registered several songs this way. Go the the Copyright Office Website for further info (I’ll go find it and post it on this thread).
The owner of the work can be you or a company, hence the copyright notice you see on webpages - C 1999 the Washington Post, or C 2000 Sue Ixnay, or whatever.
As to the registered mail – no harm in that. It can be difficult to “prove” that you had fixed the song or play in question before a certain time. The registered mail might help. On the other hand, Federal copyright registration gives you a legal presumption of precedent use by a certain date, and ownership, that is harder for infringers to overcome, this is its chief benefit.
As to what happens when you post something on a website – people steal that stuff freely, and enforcement is very difficult. And it often requires lawyers. Sorry.
