Forum Feed Cutoff date?

[pjkcards]

I am using a feed from a forum that gets a post once every couple months. It basically consists of old articles. I am using the feed:
http://www.domain.com/forum/external.php?type=RSS2&forumids=23

However, it gets cutoff after like 60 days. Is it possible to change the cutoff so I can see the entire feed from the beginning at any given time?

Thanks!

Bump, anyone? Thanks for your time.

Is this not the 'Thread Cutoff' under 'External Data Provider' in Settings?
Looks like it defaults to 30

Is it? It says keep the number small or it strains the server. I want to display a feed for all time of a particular forum. Is this possible?
