some n00b questions about custom ROMS
 

So ive had my 6800 for quite sometime. Ive done so much to it as far as installing things...playing with the registry...yada yada. I've finally decided to get into custom ROMS and have some fun with that. I've been searching all morning on getting info. Just installed some custom ROMS.... but the one thing that i had a big question about is what is the difference between No2Chem 5067 Kitchen and No2Chem 2.2pre8. Are these two completely different ROMS. What are differences. Any basic info would help. Forgive my little knowledge on this subject as i just started to get into it :)

thanks for any info.
