Are you complaining that there is a Christmas board? That would be like me moaning that there is "The Tack Room", simply because I don't have a horse!
Many people want/need to plan Christmas, often because they start buying presents now, perhaps because otherwise very popular items run out, and usually because spreading the cost over a few months is a necessity.
I acknowledge that some threads are not on the Christmas board, and it seems a lot of these are about families/ relationships/dilemmas, and they may want a wider perspective, or the opinions of people that spend a lot of time on the Relationships board, for example.
MN is for everyone, I see a lot of thread titles that I don't like or am not interested in, so I don't open them...
