Very sad news. I noticed problems but thought it was one of those temporary things.
NoGrip goes back a long, long time, back to the days when RSC and BHMS were active.
It became a haven when things turned ugly on RSC, also when BHMS was semi-abandoned.
While the NoGrip forums are no longer as populated/popular as they once were, it's still a very relevant place. There is a sense of familiarity around, with a mixture of old and new faces populating the forums, be it for the technical questions, assistance and discussions, some still also for online racing reunions.
I just recalled that it's also one of the main hubs for P&G, where there are also dedicated forums for it (which are dear to me - I'd miss those if it all became lost).
Most of all, it would be tragic for the whole scene, to have NoGrip's huge files database lost forever (some 15 years of mod files for various titles).
It was already tragic when BHMS and then RSC went down. Dozens of games had files and mods that were only hosted on BHMS. On RSC forums, there were hundreds of threads with valuable knowledge and files attached. It was all lost. I sincerely hope NoGrip doesn't repeat the sad act, and that someone can put it back online again.
