Both the Gallery and the Slideshow contain pictures. They contain the same pictures. The difference is in the presentation.
Some people like to sit back and watch things change, while others like to hunt and click for what they want. The Slideshow is for the person who enjoys watching the pictures change on their own, and the Gallery is for the hunters in the crowd.
Both the Gallery and the Slideshow do have controls, however.
It can be expanded to more, if that is desireable - but we felt having two teasers for recent content at the bottom of the front page, in the content section was enough. It is trivial to increase that number; however, it makes the front page scroll quite a bit.
Teasers for Blog Posts, Gallery Items entered, and some other content types will show up there. There is a "Pager" under that section. Previous items that made it to the front page can be found by paging through past content.
There is a block called recent blog posts.
It is on the front page, near the bottom, on the right. It will list the last 10 Blog posts made.
The site now has the ability to create polls that even anonymous users of the site can take part in. We have pre-populated some content in a poll - just to show what one could look like.
The site has a basic taxonomy for tagging Gallery Items now. We want to expand this to other content types as well - like blogs.
