nw: John Tytgat has done a little work. But you're asking the wrong question. The question is, can a RISC OS developer with a relatively little amount of experience get involved and make a difference to technologies which are in use across _all_ the ports. Once again I must insist that we are not talking about Firefox alone. The answer is most certainly yes. Some of the most valuable contributions were made by two people who never built Firefox or looked at the source - one did his work initially to support NetSurf. The important thing is to get developers involved, no matter at what level.
