Luke, sorry I forgot to respond earlier to this
thread.
We did internally discuss about this topic after you raised it and many of us moderators felt that given the low traffic in those forums it was better to have a single forum where both C and C++ questions could be asked. There were other reasons too why the moderators thought it would be better to leave it in the current form.
However, thank you for this feedback and we are glad that you are going to lurk around answering questions.
