My TAC access is via my iPhone, iPad or Windows laptop, I haven't experienced any problems. I don't recall if those having problems mentioned the platform they were on.
I have been a member of TAC since May of 2020 and honestly don't recall what it was like before the crash.
I don't have a Facebook account, so I can't say how that compares to TAC. There are a couple of other Pontiac sites that I occasionally go to, for the most part I don't see a lot of activity on the other sites.
Personally, I am very happy with TAC. Most the posting come from a small group of very talented individuals who take time and effort to help our community with detailed and often educational posts. Some people criticize the site and complain about the data loss. While I contribute an occasional post and have made monetary donations, neither is required. I do not understand when people complain about something that is free.
Could TAC be better, absolutely. Right now, I see 45 guests and two users online. If more guests would become members or log in as members and just post a little bit about what they are doing, thinking or working on. It would have a snowballing effect causing more people to get involved. It doesn't have to be anything elaborate.
To Mr. Bandit, and all the great members who constantly update the forum on your projects, and those who donate money to TAC, Thanks for keeping TAC alive!
