The Online Developer has now been bought by Platinax, and merged into the forums here - everything now 301 redirects from there to here.
I did try to run the boards there, but I was too stretched thin to develop it, and the only thing it seemed to attract were spammers.
Therefore better to focus energies onto a single board covering the subjects, as there was a lot of cross-over between here and there.
It also provides a better opportunity for Platinax to raise it's profile, partly in more content, partly in now being a significant size, and also helps define us more of an "internet business forum", rather than general business forum, which I think is important.
