I have 3 site maps, need help!

Ok, ive been using VBSeo since i started my forums in March. It has really helped me outrank my competitors. Generally, when i post a new performance review on a product from x or y company, within 24 hrs, its posted on google and generally, located within the top 3 on search results.

I upgraded the forum from 3.6.8 to 3.7.4 PL1. I also upgraded to VBSeo 3.2.0. Ive since not been ranking. Ive verified the site map is being downloaded daily, its being generated daily, im just no longer being ranked like i used to. Do i have 3 site maps because of how many URL's im trying to index daily? Should i have 1 map or is a multiple ok?

I guess i would like input on how other owners have their settings, setup & some advice. Thanks!

each file can contain a max of 50k urls, so if you have more than that, it creates a new file. There's nothing wrong there.

I posted a screen of my recommended settings in my guide (link in sig)

Thanks Brian, i actually ran across your guide a few minutes after posting that and i did just about all of what you recommended, except the non www htaccess file. I was having some issues with everything on my server when i change the ht file. I had to revert it back. Your guide was extemely useful and i thank you for providing an easy guide without having to spend hours on the forum searching.
