I'll respect the rules, I'm not trying to be a category hog ;)
I just want to make sure those who are looking for the software can find it (those in the sciences are close knit and tend to say things like "hey check out Copper, its built for bioinformatic research tracking".)
Actually, a number of our customers are involved in scientific/medical research, and use Copper to manage such projects and share documentation. Therefore as a tool Copper should be justified in residing in these sections.
Similarly, the software development and design industries are strong sectors for us, so Copper assists in the project management and document management for these customers, as well as providing its own well regarded php code-base for module development.
I'll add these categories back in, however if there is still an issue please let me know.
