Picking the correct G2G category was never my strong point, but I thought they worked like this:
WikiTree Tech - related to the software, interface and organisation of the Wikitree site. Filetypes, access issues, computer problems, gedcom upload issues, and setting up of pages,some merging and categories would go here.
Genealogy Help - questions about our actual ancestors - the people and their genealogy. Births and death dates etc. When someone was born, where to find records, naming standards,
Special Projects - related to Projects. Is there a project for a subject, questions relevant to a specific project for general comment - organisation of projects and their leadership. Badges, member requirements, project outreach etc.
My first assumption was that Tree House was a fourth category - a social category, which I actually felt was lacking on Wikitree. Somewhere to share a special discovery or to chatter in a less-specific way eg you might ask what the career type 'collier' meant which is found in the census and people could give their ideas or provide their expertise, or ask whether working with potash ever led to brain damage because you are pondering this. Or the frequent vents about ancestry links which go to paywalls would also fit here.
I actually think this will be people's assumption with Tree House - that it is the general and social forum. Which would be great! I like social. It leads to involvement.
Like Jillaine, it would absolutely not occur to me to post a project question in Tree House. Unless I saw other project questions there already. This is, I realise, because I view Projects as the more serious, structured and professional side of Wikitree. Whereas to some, projects are assumed to be the collaborative, social and fun side of Wikitree.
I can assure anyone not involved with a project that they are somewhat rigourous and involve meeting higher standards, better research and a great deal of forethought. This doesn't gel with light-hearted social. It can't. If this isn't how projects are meant to be, then perhaps discussion needs to be had on this matter too.
There were definitely issues with questions being posted in the wrong sections, but perhaps a short explanation of the category at the top of each category section might help here.
I'm basically happy to use whatever we end up with, but I think Jillaine makes a good point. I wouldn't mind seeing the four sections in use - Tech, Genealogy, Projects and Tree House. It seems nicely balanced. But I always did like the number 4 .
