Aperture 3: Watermarks with Facebook, Flickr, and MobileMe

Question

I am pleased that Apple has released Aperture 3. I have not had the chance to download the 30-day trial or play with it in an Apple store yet. For those of you who have, do you know if Apple has enabled (visible) watermarking as part of the sharing on Facebook, Flickr, and MobileMe? I don't post images without visible watermarks to the Internet without one.
What I currently do with Aperture 2.x is export the images (as .jpg) into a folder adding a watermark as part of the export preset, then import them back into Aperture and then post to MobileMe, Facebook, or Flickr. I am hoping that Aperture 3 eliminates the need for these extra steps.
If it doesn't have this ability, does anyone do anything similar that might be more streamlined?

Answer 1

Thank you folks for your suggestions. I just purchased Aperture 3 and needed to create a watermark. I was able to accomplish this using the steps below.
1. Scan the watermark into the computer or create it with an editing application. (I scanned my signature into my computer and saved it as a jpg. If you are worried about someone having your signature you may want to use a printed watermark.)
2. Open the scanned image in a photo editing application. (I used Photoshop even though I am very uncomfortable with its complexity.)
3. Adjust the size of the image using the," Image Size", tool under "Image" column in the Menu. (Do not use the Canvas Size tool. It did not work for me.)
4. Place the Layers palette on the desktop by selecting, "Layers" in the Window column at the end of the Menu.
5. Double click on the background icon in the Layers palette to open a new layer. It should be Layer 0.
6. Click, "OK".
7. Next select the Magic Wand in the tools palette and touch the background of the image. Click on the background to select the background. Click delete to make the the background disappear. The watermark should remain without the background.
8. If there are any areas enclosed in a loop, like a zero or, "O", take the magic wand and select the enclosed area to highlight it. Remove this area with the delete button. You can put the copyright mark on the image if you like by typing it next to your watermark.
9. Go to, "Save As", and save the image as a psd file where you can find it.
10. Quit the application and open Aperture and go to the preference folder for Aperture.
11. Select the Export icon and activate the, "Email photo export", preset button.
12. Select edit and go to, "Choose Image", to select your watermark with the transparent background.
13. Select a new preset on the right and name your new watermark.
14. The new watermark will appear in the, "Email photo export" options.
