I'd like to do some user specified cutoff point on a per post basis without making it overly complicated. What I mean is some type of markup that designates what part of the post should show on the portal. The reason for this is there are some times where you might want to include more or less of a post on the portal.

Maybe something like, if you're posting a topic on a forum that is portal enabled then there is a button above the posting area. Something like "End News Blurb". When you click it it would insert something like and would only display things above that point on the portal.

An example:

I just discovered today that I like toast. I like it slightly brown covered in butter. Sometimes I even put on top of it.



I could eat toast for breakfast, lunch and dinner!

If I were to type that, only the text above would show on the portal.
