Hello, I am pam and have being using inkscape for quite some time... and I am more than impressed with what Im able to do with it. I use gimp/Inkscape nearly everyday along with blender at times....
I have never done anything on windows...I have not seen photoshop or illustrator or any of those high end tools.... though would love to try them out ( if I can ever afford them)

People like lapo calamari and heathen X etc have inspired me to peruse, ponder and learn these tools.
I have built some icons and have uploaded them on deviantart... http://www.pamfeuer.deviantart.com

I plan to do much more with inkscape some day and whenever I get time I am on it....

Best of luck to you guys and the entire dev team of Inkscape. THANK YOU.
