I put off right in this because I didn't know for sure if anyone would show back up.
Google does not seem very interested in indexing the side, so the chance of new people showing up is not good.
I'm currently struggling with the registration process. The web server was sending emails through Google but it appears that Google has routed my messages to a black hole. With the help from Gemini I was trying to establish a more legitimate email service using AWS, but that's not working.
The server is under significant distress by a botnet that probably originates in China that's just hammering everything. Some of the functions I've had to put behind a login requirement. That's your problem since people aren't going to be able to register.
This blog is on the new server but the other older blogs are stuck on the old server for now because of a failure to be able to migrate the blogs to the current version of wordpress.
