You can get this information from several sources. Here are some of them:
Forums

All the information is on the forums, of course. You can check the News and Announcements subforums for each type of news.
RSS

The forums provide RSS feeds for each subforum, but you can also subscribe to this combined feed that lists all of them in a single feed with some nice extra information.

You can get this same info by following PR's Twitter feed @realitymod.
FriendFeed

With some nice thumbnails and short descriptions on the FriendFeed page.

There are some other facebook pages that feature PR, but this is the official PR Facebook Page supported by the team. You should become a fan (or as 2Slick4u would say: FAN UP!) and receive PR news in your Facebook News Feed.
MySpace
meh...
In-game News Ticker

Don't forget the PR News Ticker at the bottom of the in-game menu. It gets updated with some of these posts, showing newer ones in blue, older ones in grey and important ones in red.
We will be compiling all these highlights in "Highlight Reels" posted (hopefully) more regularly on the homepage, so keep an eye for them as well.
