I’ve resisted “yet another local chat”.
This was partly because I wanted to limit the “scope” of all the things that had to be done before going live, but also partly because I find it easy to lose track of all the different places you can talk about things.
However, anoek has showed me the way to easily do a local chat, and I can see that it would help with this kind of problem, so I will put it high on the “now what?” list.
