I think there's plenty of room for advice on Philips and the derivatives, so I don't have a problem with the 'split'.
However the notion that the old forum should go soon seems rather short-sighted, particularly if a separate Philips sub-forum is proposed. With some exceptions we don't have the regular contributions to the forum from the experienced people who made the old forum such a useful point of reference, so where are other newer people with Philips problems going to look for advice? Judging by the apparent lack of searching of the old forum by new contributors, I can't agree that all useful information has been extracted.
If senior management are considering starting a Philips forum, can you not adapt and open up the old forum again with all its history? Failing that, seeing as you're asking for moderators, can the database be preserved for off-line reference to whoever you choose? Otherwise, can one of us with some interest be identified to host the old forum, if it's space that's the problem? I assume there's copyright issues but surely these can be overcome.
