Like the program, although it does seem complicated. However, I keep receiving error messages when I send docs to be signed, and when I send it in I receive a message saying it is on our end. I would like to use the program for many things, especially getting signatures, although it seems that isn't included now and is additional cost, so I may go to authentisign

What do you like best?
I love that I can alter a pdf with just about anything. I can also send forms to my clients to e-sign through a secure site. Often I use it to sign documents that are sent to me as well.
What do you dislike?
The only drawback that I have is if I upload a document and want to use it for different customers, it doesn't save each one individually.
Recommendations to others considering the product:
Buy it!
What problems are you solving with the product? What benefits have you realized?
If I can't get a real-life e-signature I turn to PDFfiller to get the job done. My clients benefit from the secure site when I send sensitive documents to them.

Choose File > Import > Image Sequence... and navigate to the Albedo folder. Select the first image in the sequence and then click the Open button. Specify the Sequence Options. Use all twelve slices, beginning with the first slice and incrementing by one. Do not scale the images.
Align the images Basically you just need to check a few settings then click on some bright stars in the image and Image does the rest. The details: In your image sequence, click on the align button and read the instructions that pop up. Click on a few stars, right click when done to start the alignment process.
Combining stacks Just open each image stack separately, then run Image > Stack > Merge Channels..., assigning each image stack to the desired channel. The result will be a composite of each respective plane.
Hold the alt key down when moving or resizing to force the location and size to be displayed in pixels. With Image 1.42 and later, hold the control key down (command key on Macs) to resize around the center. With Image 1.43 and later, hold the alt down to constrain resizing to the current aspect ratio.
Open your 3 images for the 3 channels in Photoshop. Copy two of them into the third — select all (CTRL+A in windows) and copy (CTRL+C) and paste it (CTRL+V) into the other file. Now you will have your 3 channels as layers.
In Photoshop, choose File > New. ... Drag an image from your computer into the document. ... Drag more images into the document. ... Drag a layer up or down in the Layers panel to move an image in front of or behind another image. Click the eye icon to hide a layer.
