What Nickelicious says is correct. You can convert Reform and you will be recognized as Jewish by almost everyone. Don't let a few bad folks let you think that since they follow more rules they are better, they are just limiting themselves and they are far from perfect. To be recognized by Orthodox you need to convert orthodox but their lifestyle is a pain in the ass and they are held up on rules and not the spirit of the text they read (in fact they pretty much quickly cruise through their prayers everyday hyperspeed without thinking about it).
Nickelicious I like all this sex talk. I believe you are correct. I like how it is written out how often a husband and wife should have sex according to the profession of the husband (poor merchants never get laid). That stuff is just for fun and not really that important since it is pretty archaic.
Cougar with your Greek Orthodox background the main thing you need to give up is that you can not believe that Jesus is the son of god. If you think he was a swell guy but not divine you can join the club. Jews for Jesus and like groups are pretty disliked amougnst the Jewish community (because they aren't Jews they are Christians)
