HTAccess mod rewrite issue using QSA

Question

Hey, I want to add a parameter to a URL but currently it isnt showing in the $_GET global. A snippet from my htaccess file is as below:

RewriteRule ^account/blogs/([0-9]+)/([^\s?]+)/?$ /account/blog.php?blogId=$1 [L,QSA]

Then in my php code i want to add a link such as:

/account/blogs/1/ThisIsWhereTheTitleGoes?delete=1

The wildcard (any char but space) option is for the blog title as i never know what it would be. I know want to add a query string param on the end such as ?delete=1. I however dont want this as part of the rewrite.

Does anybody know how to so this? Thanks
