RSS Output (Format)

[Allenport]

Hey I was wondering if anyone knew how to edit the RSS output from the forums?

Under News Feed I would like to be able to edit the Info and format it better. Is this possible?

Thanks

JJ

Example
How it is now:

{Thread title}
Forum:{name of forum}PostedBy:{username}
Post Time:{Date} at {time}
{Random date i have yet to figure out}

How I would like it

{Thread title}
<b>Posted by:</b> {username}
<b>Posted:</b> {Date} <b>at</b> {time}

--------------- Added [DATE]1254285527[/DATE] at [TIME]1254285527[/TIME] ---------------
