couple ways you could do the gallery. you could make your post and then go to the page and put it in edit mode. then just add a galler block of your choosing.

Or you could use a custom page_type for that post, or all posts, and add a global area:



Then go to the page at least once to refresh the cache, and then go to your dashboard stacks area, and add a gallery block to your new global area.

for the date issue, you can use the date picker in the options pane when adding/editing a post. Set this date to any date desired.

you can also just go to the page and edit the pages properties and change it there.

Thanks chat, just a question regarding: "...use a custom page_type for that post, or all posts, and add a global area:"
I think you mean I should add a new custom page site. Can you please explain which kind of handle I should use? Is this the pb_post handle? And where do I find this site later on to paste the code for the global area? (Sorry, I could not find a relevant "how to..")

you would basically do this:

1-copy the pb_post.php file to your root /page_types folder and rename it to "pb_post_gagllery" or something like that.
2-edit your new file and add the code I posted above for a global block area.
3-go to your page_types area in your dashboard and manually add a new page_type called "pb_post_gallery".
4-create at least one post with this new page_type. then go view it. This is a dummy post just so you can go view it, so that C5 will register the global area. View a page with a global area is how C5 registers them. you can delete this post as soon as you view it once.
5- go to your stacks area of you dashboard, and add blocks to your new global area.

all done.

Any page using this page_type will now have those blocks wherever you put/style that global area.
