CiCiVacation I'm looking into it. I was aware that location is useful information for this forum's users, so it's been on an informal "check later" list.
The forum core itself is very minimal, including the user profile, as you've probably seen. Most of the extras are from several extensions it ships with and a few additional extensions I added to improve usability. The image uploader/media manager and emoji picker are good examples of the latter.
Anyway, there are some possibilities. We can add a user bio. There is an extension that optionally allows adding first and/or last names that we could abuse. (And maybe more fields. I haven't looked yet.) We could also fall back on GeoIP, but again, I haven't looked at it yet either, so I don't know how granular it is. It wouldn't be much use if it just says "US". 🙂 I would prefer location info to be optional anyway.
And, of course, anything could be added by writing our own extensions. I'm familiar with the PHP the backend uses but not the javascript-based Mithril presentation layer, so there would be a learning curve. It seems to be template-based, so it may be doable without getting too into the weeds but @blown_dry keeps me somewhat booked with new DAHLIAaddict features and updates. 👨💻 She did give me a couple days off to setup a forum, so there was that break. 😉
