Since some of the jobs I am applying, require that I know ASP.NET and C#, I have decided to build a website.
I installed successfully ASP.NET with C# on my Mac OSX.
I made them using GIMP since I do not have another graphic editor available at the moment.
I would say that GIMP provides quite a different and unique user interface.
While the user interface is not intuitive, this is the best open source software available for image editing I know so far.
