After VB-JUNE, 2007, I am so excited, can I do I-485 by myself? tamade2007-05-15 19:13:40

My I-140 (NIW) was approved September, 2006. I did by myself. But I am not confident to do I-485.
Can someone who does I-485 him or herself provide some information? Such as, special cares should be taken. Thanks.
