What would be the purpose?….really long titles will only look bad on site and have little to no SEO purpose I think.
		
	 
	
	
	
 
		
			
	
	
		
		Hi, Peter thx for a response! 
The purpose is the issue of the forum. It is a discussion forum about haiku. If you don“t know them: little poems written usually in 3 lines. To display them as topic I need  a textarea field for the 3 lines. Meanwhile I have a solution for the entry title and could substitute in the form-topic.php the input label as textarea. To display it with line breaks I use the css white-space tag. But there is still one problem I can not solve by css-rule, if you are common with that, perhaps you have a hint for me. You can se that:
Here the entry-title is displayed corect with line breaks:
http://15.haiku.de/forums/topic/ein-erstes-haikuhier-eingetragen-und-dannweiter-verfolgt/
but in the topic-list view I cant find the correct css rule to make the breaks correct:

you should tell your users to display the title of the haiku as the topic title while the content be the actual haiku.
