Drupal 7.x

I have two content types one is:
Ship and the other is Room
One of the fields in Room is Ship, which is related to the Ship content by using the Node Reference module.
When I go to a ship node, I need to display also teaser content of the rooms of that particular ship.
How can I do this?
I have views module installed, but am not sure if I need it to achieve that..? If yes how?

Firstly if this is already covered elsewhere, my apologise. I have been looking for help for quite some time now and I don't know php which is what I think is letting me down now. I am using Drupal 7 as well if this helps and pretty new to it all.

What I am trying to achieve is for a specific content type (article) to output its node display in this mannor:

Hi.

I have added an Aggregator block to the content area on my home page, so show posts of a separate blog system I have. BUT it shows as an unordered list of just titles. I would like the title, date and summary of the blog to show.

I have searched and searched I just cant find out how to modify the output of the aggregator to show this.

Does anyone know?

Thanks

Hi, hope I have this in the right forum.

I am building a website where users pay a monthly fee to access information that is updated daily. I am putting the content they pay for on a URL alias, how do I make it so only paid subscribers can access that page?

I am new to website design.

Thanks in advance for any help.

I've themed and developed in Wordpress. I find the method within that system limited but extremely accessible for designers. I've started learning how to use ModX and it's theming system feels surprisingly versatile but accessible. I'm concerned about Drupal's theming system. It's taken me more time to learn how to theme in Drupal (properly) than in either of those aforementioned systems.

The title says it all... unfortunately, I haven't found a solution for this on Drupal 7. I was able to use the SSO module on Drupal 6, but it is not being actively maintained. Neither is the multisite_login module.... both Drupal 6.

Anyone have any ideas? Suggestions? This is looking like a pretty big road block for my Drupal 7 install.

Thanks!
