I've been wondering this for a while, and after searching, found no answer.

With a form for HTML/PHP, for example, the message posting form here on the forum, how do you make the code read new lines and save them as
s, rather than as one long chunk of text without new lines?

My forms, as they are, would ignore all the new lines in this and make this into one very long line.

Anyone?

you could use nl2br()

(If I understood the question correctly)

You did indeed.

Thankyou profusely, kind Icelandic sir.
