Options +FollowSymLinks
RewriteEngine on
RewriteCond %{HTTP_HOST} ^boundarysports.com

I undertsand your caution. Sometimes when I go to update my site I fear an unfavourable response.
Good Luck

To overcome this, I suggest you to try to get inbound links as much as you can. The more you will have the inbound links the more chances you can get the higher PR. Usually, the updation held once in three months.

"but my page rank drops 3 to 0 and even i lost my position in google SERPS."Is this happened at once or gradually?
there is a huge difference of algorithm between Google and other search engines, Google don't love too many links at once , but on the other hand Yahoo loves blogs links and don't care about PR of link.

You can get back your PR by following these steps:
Here is the list of important Google SEO ranking factors to consider:

1. Age of Domain: Age of URL is very important. If you just bought your domain a few weeks or even months ago you have a long road ahead of you. If your website has been online for several years, chances are you have an established business.

2.Domain Hosting: Where is your site hosted? Find out through your hosting company what continent or country your site is hosted in. This can often times play a large role in search rankings. Always use a reputable hosting company.

3.URL Structure: Make sure your URL structures are very clean. There should not be any random strings of characters at the end of your URL’s. This is part of the onsite search engine optimization process as well.

4.Content: Content is very important. To start make sure you have text on all your important pages, then make sure it is good text consisting of your targeted keywords spread throughout naturally.

5. Internal Link Structure: Make sure your inner pages are linked correctly. Visitors should have easy made pathways connecting to your other pages from every page of your website.

6.Keywords: Make sure your website is optimized using your keywords. This means any alt tags for images, meta page information and existing content at the very least of things.

7.Outbound links: Make sure the websites that you link to are 100% relevant to your business and industry. If you sell animals toys but you are linking to a site that sells shoes that is not very relevant and over time could really impact your rankings.

8.Inbound Links: I know this was a list of my top 10, but I felt I had to mention inbound links. The key here (speaking as a white hat SEO person), don’t buy or exchange links. Market and promote your business online to build visitors to your website over time. If you do, then the relevant links will follow!
