Phew!

I just went over all of the links in the list in the first post, added some new ones (GR Wiki, GRPL Discord, FormulaGR, R-Garage), updated some addresses and moved the dead links to a separate list to make browsing easier.
I've kept the links with some functionality in the main list but marked problems with red color. There are also some sites that I know/hope will be back kept in the main list.
In case you wonder, I wanted to keep the dead links to preserve the memory of times when we had many more sites.
If you still know of any working GeneRally sites that are not in the list, post them below.
