hi im looking on how to make a wysiwyg textbox where i can have each line in the textbox wrapped with <p>

and also how would i bold everything before the ":" on each new line
kinda like tumblr.com "chat" posting box except they make it into a list, which is not what i want

I think they are using TinyMCE for their wysiwyg textbox.

Here is TinyMCE's link http://tinymce.moxiecode.com/

Here is the link for their example: http://tinymce.moxiecode.com/example.php?example=true

With TinyMCE you can specify how many and which buttons you want to appear on the toolbar. You can also specify where the toolbar will appear (Top or Bottom of the textbox). You can also customize how the toolbar looks like.

I have used it before on some of my projects but my problems with it is that it takes very long to load, so I switched to FCKeditor.
