To be fair Rob, it's "the hunt for cold" because it's what the vast majority of people are looking for in winter. (Though it should really be called "the hunt for snow"). Therfore most posts will naturally lean towards cold prospects.
If a route to cold wintry weather appears in the charts, in a country more prone to Atlantic westerlies, it's fair to assume that people will highlight this, even though most of the time it fails to materialise. (The "hunt for mild" would be like looking for a bit of hay in a haystack )
On the other hand, if the foreseeable outlook is mild, it is still the model thread and as you say, posting charts showing mild weather shouldn't be a problem to anyone and are perfectly entitled to be in this thread, as much as any showing cold.
