Forum RSS Feed Title?

[webmastersun]

Hello,

I have just used Feedburner for forum rss instead of using vBulletin rss feed for any forums and sub forums on my forum, but having a small issue about feed title, I want to know where to edit and change RSS feed title

Examples about my forum rss

http://www.webmastersun.com/external.php?type=RSS2&forumids=10
http://www.webmastersun.com/external.php?type=RSS2&forumids=11
http://www.webmastersun.com/external.php?type=RSS2&forumids=13

All titles are showing "Webmaster Sun - The Largest Internet Marketing Forum & Marketplace" + "Sub/Forum Title"

But I want change to "Webmaster Sun" + "Sub/Forum Title" to make them cleaner

For example, code in a rss link:

<title>
<![CDATA[
Webmaster Sun - The Largest Internet Marketing Forum & Marketplace - Social Networks
]]>
</title>

Just want to change rss feed title by a custom name but still keeping main forum title.

Any suggestions where to edit?


Thanks
