The bots have adapted again to bypass the registration question (no surprise given agentic ai). As a result, almost all non-US IPs used at registration will be rejected.
If you have a problem registering (and you are local enough (i.e. road trip driving distance, active fb user with sph trips showing, etc.) or have history with sph) you can still email me as described elsewhere on the home pages outside the forum and we can get you set up.
