jCore handles contents differently. You can't define category for a content, your category is the menu item you put your content in. For e.g. if you have a menu called About then you just go to the Content Management section of your admin and click the Posts icon on the right of the About menu item and start adding your posts/contents. You can have as many content/posts you want in a menu.
In all your content you are free to use the content codes which will enable you to include a module (or only a part of it) in your content or even other posts For further details on content codes please see Features -> Content Codes.
The content editing is done by a WYSIWYG editor. More preciselly it is the well known ckEditor with upload enabled, meaning you can upload pictures/flash files directly from the editor and include them in your content.
When uploading a new picture from the Editor a thumbnail will be generated automatically which will be the size you define in your Global Settings area in the admin, to access the thumbnail, just prepend thumbnails/ to the path before the date (200910). For e.g. if you upload cat.jpg your thumbnail would be thumbnail/200910/cat.jpg and you can just add a link to the large image 200910/cat.jpg this way when people click on the image they will see the large version too.
You can also embed flash files into your content by simply uploading the swf file directly from the editor and defining the width/height for it and that's it.
Note: Uploading from ckEditor is supported starting from version 0.5.
Besides the editor you can add attachments to a post by using the attachment icon on the right side of a post, these attachments will show up at the bottom of your post unless it's not a Partial Content in which case you would first have to click on the posts title to see the attachments.
You can also attach pictures to this posts regardless of the WYSIWYG editor, the pictures attached will show up differently depending by the display options you select for a post, for e.g. if you select Partial Content only the first on of the pictures will be shown on the left side of the post while if Partial Content is not checked the pictures will be shown on the right side of a post below eachother but from css you should be able to place them to any place you want.
Partial Content is used in the situations when you would like to have a News page where the news should show up with a head part of the content and then a read more link would take them to the whole part of it. In this case to define the end of the head part and the start of the rest of the content please use the Horizontal Separator in your WYSIWYG editor, just click the horizontal separator line icon in the editor and that;s it.
For blogging reasons you can define keywords for your posts too, these keywords will be used to generate relevant posts and/or to generate a post keywords cloud.
You can also have announcements on your site as you can define for posts a start/end date to, if these dates are defined the posts will be sort by Start Date and when the End Date is reached the posts will automatically dissapear from the site.
Posts also can be linked to blocks meaning that lats say you have a Block on the left side of your site where you would like to show the contact info of your company, to do that just go to your Main Menu, click posts icon on the first menu and create a new post by selecting in the Display Options the Left Block you have created for this information and checking the Display On All pages. This way the contact information you just entered in your post's content will be shown on the left side of your site on every page. To have different posts in a block for different menus just add those posts to the defined menu and that's itt. You can even have a content form a menu shown up on the main page, just check Display On Main Page in that case.
Comments can also be associated to posts, if you would like to enalbe people to add comments to your post just check Enable Comments in the comments options.
Using this content management system you should be able to create pages like, News, Announcements, Blog, About, Welcome and so on, almost anything that a usual client would need.
