Sometimes I have difficulty deciphering handwriting, in particular, signatures. I recently found an article that gave a great tip for helping to read those scrawls. Using a clipping program (Windows 7 has a snipping tool built-in), capture the signature and save the image. Now, using an image editing program (I use PSP X4) with your image open, select Effects, Geometric Effects, Skew. The skew direction will be based on the slant of the signature and by adjusting the skew angle, you can rotate the signature to make it easier to read.
