I don't even care what theories you have. You are a winner for this attitude.
This is the reason why I go onto forums. Not just for the predictions, criticism, but being able to meet people as wise and open-minded as you are. Thanks for posting that, I wasn't even having that great of a day and that helped make me appreciate how I can contribute to forums by being honest with myself, learning from others, and just being a passionate geek. I don't mean to sound conceited because I'm saying all of this because of why you typed that, not just because of being praised in general.
Anyhow, I was a lurker for a couple years up until last month, so I understand the pressure of not being able to make an account due to various trivial reasons lol. I'm also a fan of Jojo, and there's a thread in the Other Manga/Anime section where people post frequently per week if you're interested (although I'm sure you've checked it out already during your lurking days lol).
I hope you enjoy your stay here, Cabbage; I can tell that you've already got great character and will be a memorable contributor.
