Thanks for your comments.
To be honest, maybe I was expecting a little too much that possible contributors would do a bit of research on what's required, for example the format of a Tangram style file, which is the main thing which controls what is on the map; so that if people wanted to add new things to the map or tweak others, they'd research how to do this in Tangram and have a go at tweaking the file.
You are right that I have said nothing about how I import the db though. I do use a modified osm2pgsql style file for the version on free-map.org.uk, though the version on the OSMUK server uses the unmodified file. I have now added the scripts I use to create the database to the repo.
Issues like the slowness of the map are down to the fact that I do not yet do any caching, plus both servers I use (one donated, one paid-for by myself) are fairly low on memory. Again, the whole point of the demo as it stands is a quick and dirty proof-of-concept to experiment with vector tiles.

At some point, at Adam's suggestion, I will probably setup a poll on Loomio to gather ideas for features.
Thanks for this, but I suspect that a bit more information will be needed by anyone who might be thinking about helping with this. Currently the "What's needed" section of the readme is a bit "Monty Python: how to play the flute" ( https://www.youtube.com/watch?v=-1sM29zGxeo ). As just one example, I'd expect that the osm2pgsql database needs to be imported with a particular style file to decide which columns are created. Maybe that's the default osm2pgsql one, maybe it's a different one such as https://github.com/gravitystorm/openstreetmap-carto/blob/master/openstreetmap-carto.style , or maybe it's a cut-down one to minimise database size - but without that information, no-one is going to be able to reproduce what you currently have at http://22.214.171.124/ or https://www.free-map.org.uk/ and investigate why things are as they are there - for example why are some things shown and not other, why does the screen only take up a quarter of the browser window, why is it so slow (is that a server or a client side issue)?
I appreciate that this is only designed to be a proof of concept - but surely the purpose is that people will see it and say "that isn't exactly what I was looking for but I can change it to do X, and Y, and Z"? I don't think that that's really possible right now.
