Re: Posting questions
Ok, thanks for clarifying.
To sticky the post, you can go to the "Posts" screen in your
WP Dashboard, select "Quick Edit" for the relevant ad, and then check the box that says "make this post sticky". You can also sticky an ad from within the edit post screen from within the "publish" settings.
By default the categories are in alphabetical order, however you can try using a plugin such as this one:
http://wordpress.org/extend/plugins/my-category-order/ to achieve an order you prefer. I haven't used this myself so can't comment on it.
