We're not asking for a RISC OS "core" programmer, because that's meaningless. The core is entirely OS-agnostic. Moving features from the already well-developed RISC OS front end to the core means that they can be debugged (RISC OS's debugging tools are shockingly poor by comparison to those available elsewhere) and so other front ends can take advantage of them without having to reimplement them themselves. This should lead to a better NetSurf all round; for RISC OS and other platforms. Unfortunately, nobody's touched the RISC OS front end in over two years, which is why we're asking for somebody to.
