Getting rid of “Feed:”

I set up wordpress, then went to set up the rss feed. All is good, except that I can’t find the footer (and I’ve tried /wp-admin/admin-footer) to edit it to http://mysite.net/myfeed.xml – it still comes up as feed:http://mysite.net/?feed=comments-rss2

Naturally, Firefox tells me it doesn’t recognize the protocol, “feed”. Well duh! Neither do I! But I’ve searched the wordpress files high and low, (for the string: ‘feed:http://mysite.net/?feed=rss2’) and I can’t find where I need to change the reference to allow me to link to my created rss xml page.

I realize that this is an extreme noob question to those of you in the know. I appreciate your patience in advance. I also looked through the support docs and didn’t find the answer.

Additionally, is there somewhere that has an idiot-proof guide to setting this up, and getting a RSS feed going?

Thanks,
Box
