compress blog entries

WordPress Message Board Questions:

I have two wordpress blog sites.

One has the Theme Style FINDER. It automatically compresses the article into a title and one paragraph with a link to the whole article

The other is ECTO and it lists the whole blog article one after another down the page.

How can I compress them like in the FINDER theme style?

I tried putting this “<!–MORE–>” into the first paragraph but it didn’t work. I tried it with and without the quote marks. Do I need to put that into the html inspect elements type page? If so how do I get to it?

Thanks

Don
