I'm reading the instructions here on mapping my existing domain to wordpress by changing the DNS's.Is there anything I need to be concerned about like losing my email address functionality. I'm reading in the instructions where it says any email addresses I have under the current DNS may stop working when I change DNS's. I'm a little fuzzy on what I'm supposed to do to prevent this.
Also, I recently loaded up a new site and did 301 re-directs from the old site pages to the new. I see in WordPress's mapping instructions that wordpress automatically removes the "WWW" from any web addresses. This tells me I have to change to 301 re-directs?? Is this correct?
The blog I need help with is vanderloo.wordpress.com.
