Sorry for the old-school terminology and mis-terms in this message as I have not had a problem like this since my dumb-terminal days (I'm guessing that long)

How does one add the proper carriage returns to a post?

I have these three lines, with a new line on each but formats as one paragraph: This is line 1. This is line 2. This is line 3.

The only way I can separate these lines is using an extra carriage return between each line which looks horrible.

This is line 1.

This is line 2.

This is line 3.

How do I get the above lines to show up without that extra new line between each?

Thanks!
