I think sinbad's right that the test patches have split the userbase a bit. I used to race on the Old Men Racing server more than anywhere else, but they on a test patch now and I got sick of swapping .exes so I'm just going to leave it until X comes out.

That's not to say that there is usually plenty of variety, because there plainly isn't.

just make a copy of your LFS folder and after install in one the patch and you can easy use both

just make two shortcuts, one for LFS_W and LFS.exe (W24), it will work fine

It was a pain in the arse though, because I was using RadLinker to set up AA and AF for LFS, so whichever patch I wanted to run, I had to re-name it "LFS.exe" so my radlink would find it.

I just got sick of tossing about doing that when nine out of ten times there wasn't a server worth joining in any version of LFS anyway.
