Capture does not have a text editor. There was a utility on the web to add signatures in capture but I have not been able to get it to work. You can edit the metadata and add copyright, owner, contact etc. information. I have mine set to include the edited metadata on import in VNX2.
Metadata does have the camera shot information, but one can add other metadata fields that includes the copyright for Exif, IPTC, andXMP.
The newer Nikon cameras allow for the inclusion of the copyright data while older cameras you can use the comment field for the copyright information if desired.
Nikon Transfer included with Nikon View NX and Nikon Capture NX can add standard data as part of the transfer process or during editing. There are also a number of 3rd party tools that can modify the EXIF, XMP, or ITPC data.
While I use PS to add my signatures, my meta data has the full copyright information which I add when I use transfer to put my images on my computer. There is one way you can add a copyright signature without buying other SW to do it, but it will take a steady hand. Choose the Colorize tool and then use a plus brush to write directly on your image. I would blow the image way up to do this, and you will have to hand draw the copyright symbol, but it can be done, just like it is possible to add borders using the same tool.
CNX2 won't do it. For little things like watermarks and copyright overlays, I use Corel's PaintShop Pro. It does a lot the Photoshop type things but it only costs $50-70, depending on what sale you catch.
Don't have it downloaded at the moment but seem to remember I used to use the excellent free Picasa Photo program to add text after processing in Capture NX2. Must be other free ones, strange that NX2 doesn't have text in this day & age.

Not strange at all, CNX is primarily a RAW converter, not a pixel editor. I'm glad it does what it does very well, and hasn't turned into bloatware.
And you also buy it once, instead paying for ever, and ever, and ever...
