I use this forum with regard to my MG.
https://www.the-t-bar.com/I don't like it as much as the old LMC/Betaboyz Myzen forums, it's less intuitive and I don't find the search function as good plus it doesn't have the logical home page divided by subject etc. However, I guess it is modern as it was fully updated a couple of months ago, although this took quite a bit of work by the admins post update as it stopped working properly on Edge even though it was fine on Chrome.
It's all a classic example of how modern software isn't always an improvement. I've tried several new apps to replace Microsoft Money that I use for my home budget, every single one has been useless.......
