Places to ask questions?

I really have found no other place to ask. I'm trying to find a seed explorer that works with tectonic. https://mcseedmap.net doesn't really work from what I can see, especially structures don't work (which are the main reason to use a seed explorer anyways.) I have found no discord or other platform where experiences with Tectonic could be shared easily, so please excuse if this isn't supposed to go into a github issue.
