Thanks, it's helped a little, I now have 2 urls that will take you to the same content, one with community in it one without.
I don't want to have duplicate content listed, I don't know what to do with it now
This is my new .htaccess,
ErrorDocument 401 default
ErrorDocument 403 default
ErrorDocument 404 default
ErrorDocument 500 default
<IfModule mod_rewrite.c>
RewriteEngine On
# If you are having problems with the rewrite rules, remove the "#" from the
# line that begins "RewriteBase" below. You will also have to change the path
# of the rewrite to reflect the path to your XenForo installation.
RewriteRule ^community/(.*)?$ /$1 [R=301,L]
RewriteBase /community
# This line may be needed to enable WebDAV editing with PHP as a CGI.
#RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteRule [^/]+/([\d]+)-.+-([\d]+).html showthread.php?t=$1&page=$2 [NC,L]
RewriteRule [^/]+/([\d]+)-.+.html showthread.php?t=$1 [NC,L]
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^(data/|js/|styles/|install/|favicon\.ico|crossdomain\.xml|robots\.txt) - [NC,L]
RewriteRule ^.*$ index.php [NC,L]
</IfModule>
I also have a similar one in the community dir
