I don't know if anything like this has been posted before, but I thought I'd share something I just discovered -- a poor man's watermark.
1) Create a new doc with transparent background. I'm using 400(w) x 200(h).
2) Using the type tool, select your font preference and a size. I'm using 60pt with the Scriptina font. Also choose your preferred foreground color -- black is easiest to work with, but white may be preferable for the final result.
3)Click inside the doc window and type your name (or whatever you wish to appear in your watermark). If you want to use the copyright symbol, hold down the ALT key while typing 0169 on the NUMERIC keypad. You can have carriage returns.
4) Next, if you don't have the signature centered and/or sized properly in the window, select Free Transform to move and size your signature.
5)If desired, you can add a layer style such as emboss, etc. I'm using pillow emboss with smooth technique. I've also selected black with 75% opacity for outer glow. Play around a bit to get something you like.
6) Save as a photoshop document (PSD).
The signature is ready to be used as a texture on your pictures.
1) Open and edit your picture as you normally would.
2) Before posting to an online forum, you can add the texture by choosing the Texturizer tool and selecting "Load Texture" and navigating to your signature file.
3) Play around a bit with the scaling and relief to suit your liking.
Hope this is understandable/reapeatable. I wrote the instructions as I was working through it myself, so it may require a bit of tweaking.
