Flash.
OK, First off all, I dislike Macromedia’s Flash intensely, that is one of the reasons that it is not anyone on this page, however it has now come to the point where I should really get out and learn it - most company’s require it, so I guess if I go elsewhere, I’ll have to convince them not to use flash AFTER I’ve joined there company, all the same, I’ve installed the latest version, and am now going to start learning it… what fun.
