Surely the point is to be somewhere supportive for people working in the same profession.
They aren't necessarily campaign groups.
And in the end being more visible is only every how much others whether as individuals or as the media report what they say or are doing.
But primarily, which is why I bumped this thread was in case not everyone was aware that might be a SEEN group relevant to them that they could join for mutual support.
Of course, anyone who thinks an issue should have a campaign could start a campaign group and you could join that, or start it yourself!
