One of the pieces of software I use is called TNG (The Next Generation of Genealogy Site Building). Here is the URL: https://tngsitebuilding.com/
I have this installed on my dev environment which runs Arch, Nginx and Mariahdb. I have two other tests sites that are Wordpress test sites. The wordpress sites that I have running, tend to run a little on the slower side, even with caching plugins and all of that. The TNG site on the other hand run blazingly fast, it is impressive. I used to have that site live so family members can look at the information. TNG is built with PHP and the developer has done an amazing job with it and they continue to not disappoint with improvements.
In the past on my live site, I used Wordpress alongside of it to write blog posts and such. Someone created a plugin so that usernames and data synced up and such. My crazy idea is to see how hard it would be to build a plugin for Nodebb to work with TNG. It would be nice so if a username was created on either one that you would be able to use the same username on the other. It would also be nice to be able to pull in information on a family member into Nodebb and such and be able to link information.
The idea would be that you could create a category for the different families using their surnames. Those can be created manually, but then when someone creates a new topic they could search and link the person they want to talk about. That link could pull in some of the information about that person as a little summary and then when you click on that person in the post it would bring you to the TNG site where you could see everything about them.
You would want it so it only is able to pull information from people that have died and any information from living people would not be available. This is my crazy idea for today, but I think the speed of Nodebb matched up with TNG would be pretty amazing.
