I have one question about wordpress, help please

The links under catagories will show up automatically dependant upon how you catagorise the posts when you create them.

The Links for Review you can do manually as follows:-

In your Wordpress Admin, click on the 'Links' button on the left hand side and then create a category within links called 'Reviews'.
Then (still under the links tab) click on the button 'add new' to add the links to the individual pages.

Once you have added some links, Click on 'Appearance' and then 'Widgets' in the left hand menu. Drag a links widget into your sidebar and from the dropdown menu select Reviews. and then save the widget settings. That should then show your review links.

I hope this helps, let me know how you get on.

It looks like "Categories" in your sidebar is actually your "Pages" widget but you named it "Categories". Pages don't normally show up under Categories.

If you're talking about adding new Pages (as you typed pages), as opposed to Posts, then yes, each new Page will fall under Categories as you currently have your widgets set up this way.

The "reviews" section in your sidebar is actually your Categories sections, your real categories inside wordpress. Every time you make a POST, you will need to assign a category to that post and whatever that category is called, will show up as a link (to that category) in the sidebar under "reviews".

If you are looking to have links to specific POSTS you make (not PAGES), then you'll need to add the widget "Recent Posts" and all your latest posts will appear in the sidebar, however, not under "reviews", unless you actually name the Recent Posts widget "reviews".

If you do what creativetoria is saying, you can link to specific posts without having to rely on the most recent posts. By adding the full url to each posts in the Links section (normally your blogroll).

An alternative is to create Pages, as you initially enquired, and you don't need to mess with Links, or Recent Posts. Simply create a page and rename your Pages widget from "Categories" to "Reviews" and rename your "reviews" widget to Categories. You probably just have it a bit backwards

Hope I didn't confuse you lol. Either way, you can customise your sidebar pretty easily.

thanks for all the help guys, its really appreciated
