What are some suggested editors for modifying SVG files?
A number of apps (both SVG and general drawing) are listed on the Inkscape wiki. In addition to Inkscape, other SVG-capable apps include Corel Draw, Sodipodi, Adobe Illustrator, Jasc Web Draw, Sketsa, Express Animator and Sketch (aka Skencil). Other SVG apps can be found by searching freshmeat.net for “SVG”.
