b2e >> wp email/mms features maintained?

Hello, I am new to wordpress… In the process of deciding which one to install (geeklog, serendipity, wordpress, my bloggie, b2evolution etc) I decided to go with wordpress hoping it’d be the right move… somebody told me that worpress is the evolution/continuation of b2evolution, is that right? if so (or if not) can somebody tell me where I can find the neat email/mms-to-blog feature that b2e advertises on the software as one of their features? is there a plug in for that? thanks
