Hello Xynix, welcome to Wikipedia.
Thanks for your excellent article on Beta Israel. As you might have noticed, I've marked it to be merged with the existing article on Falasha. You've got some info that's not in the Falasha article, and one or two things don't agree, such as the numbers - I don't know enough to say what's right.
If you feel strongly that the main title for the article should be Beta Israel and not Falasha, I would suggest discussing this on the talk page for the Falasha article.
