Hello. I'm just starting out (literally, I have never played an online multiplayer game ever) and I just had a few questions.

a) I have JJ2 v1.20. While it is mentioned in many posts that v1.20 can be patched to 1.23, the Necessary Downloads section on jazz2online only has a patch that says 1.21 - 1.23. Do I use this patch for my own game as well?

b) Although the JCS of v.124 (TSF) is not compatible with 1.23-, can I use v.124 to successfully join, play and/or host 1.23 games and lower?

c) I was wondering which levels would be best to download with so that I could participate in some games.

Thanks.
