I tried to enter:

src="http://a.tiles.mapbox.com/v3/mroswell.house-agriculture-committee.html#4/32.713/-96.240" frameborder="0" width="640" height="490">

Unfortunately nothing displays. And when I go back to edit the html, it's gone as well. One of your community pages, http://nationbuilder.com/coordinating_nationbuilder_with_other_cms, says that iframes are allowed. Is that no longer true? 

It's very imortant to me to be able to display this content on my site. (MapBox is an awesome service.)

UPDATE: I have determined the answer to the first half of the question. Will document in comments, and will create a separate question for the randomizer issue.

----

For the blog whose slug is "blog" I'm successful with theming like this:

{% for post in page.blog.most_recent_blog_posts limit:5 offset:1 %}

{{ post.published_at | date: '%b %d' }}

{{ post.headline }}

{% endfor %}

But what if we have a second blog whose slug is "recipes?" How do we pull most recent posts from there? (I also want to randomize the selected blog posts.) 

So, seeking assistance on both fronts: accessing most_recent_blog_posts for multiple blogs, and randomizing their display (which I imagine will be done with jquery.)

Is there a wildcard character for search?

I want to be able to search "field is not empty," "field is empty," and search emails addresses "%@coca-cola.com" (any email @domain.com)

Thanks!
