JS feed help

[PamelaE]

Hi,

We want to implement the js feed on site and I have read some threads here but dont understand how to do the following:

Specify:

Number of threads to show
Only show posts and not replies
only show post title and username
Posts shown from a specific forum

I did a test of the JS and it works in its 'raw' format but my IE blocked the content in pop-up blocker? is there a reason this would happen

I basically want to replicate what we already use on one of our sites:

Thank you
