I unfortunatly have another perspective on the conversions issue. I am not adopted, but my mom converted to Judiasm before i was born. She did the whole body of water thing (the reform conversion). I later went to a Jewish school for 5 years (in HOng Kong). The school was run by the orthodox synagouge in HK, and the Rabbis for the most part there were very rude to me because they didnt consider me 'Jewish'. They even created a 'Bat Mitzva club', which all of the girls in my grade, the grade above and below me were invited to join, except for me.
This was very hurtful to me because i didnt see myself as any less jewish then any of the other kid, infact, we were more religious then half of them (my dad is israeli).
Well, so i guess i went off topic a little, but jsut a warning, some orthodox synagoges can be VERY unwelcoming to people who they dont consider Jewish. However, this is may just be the case for synagoges outside of the US .
