Freetext field - line breaks or textarea block?

[earwax]

I created a new freetext field in the user's preference so each agent in a given group can customize their signature. I am able to use their custom individual signature, however, there is no way to do line breaks in that single input field. Is there a way to do line breaks in an input block in a freetext field?

For example, my signature in OTRS looks like this:

Code: Select all

OTRS 3.0.11 Ubuntu Linux 10.04 MySQL

It should look like this:

Code: Select all

OTRS 3.0.11 
Ubuntu Linux 10.04 
MySQL

I tried doing the below but the < br > HTML tag shows up:

Code: Select all

OTRS 3.0.11<br>Ubuntu Linux 10.04<br>MySQL

Or, is there a way I can change that block type to something other than a single line 'input'? I tried 'TextArea' and 'Text' but it won't let me increase the rows. I'm not even sure if the TextArea or Text field would know about line breaks.
