<a href="http://textboard.org">?</a> in the navbar would probably be better off being something like <a href="/">return</a>
Indeed I don't remember why the domain was hardcoded. It's awful bloat. I prefer the discret `?' It's like an ``about'' page. The index has to be rewritten anyway, but it's onlly intended to give some info about the software. I have to add the board navigation at the top of the pages, something that will list all directories in /data/sexp/ it's nothing too complicated.
Besides that, I might go down the hole of building nginx manually in Docker instead of using the stock image so that I can build it with
ngx_fancyindex_moduleandngx_http_substitutions_filter_module. (Are there other modules you're using?)
They're the only two modules used and they are mirrored in my repo: https://gitlab.com/naughtybits/ngx-fancyindex
There's a slight change in ngx-fancyindex, I've redesigned the icons with cute lambdas. You can use them if you like them. ngx_substitions_filter is vanilla.
Maybe also shove certbot in there for TLS while at it.
Nowadays it's a must have.
Fossil is up and running (if DNS records have propagated) http://fossil.textboard.org There's only zge's sbbs.el at the moment (and no TLS) but I'll add your Docker image there if you allow me to.
