You have two sources of information for styling your posts. On top of the post form you have a series of buttons. These buttons allow you a minimum of formatting with no knowledge of style coding in either HTML or CSS.

inserts the tags to create italics.
inserts the tags to bold the text.
is absolutely necessary to introduce quotes from a source that are a paragraph or more long. You wrap the text in tags in order to get the following effect:
culturekitchen is a community blog aimed at cultural creatives who believe progressive activism starts in the kitchen, the bedroom, the home, the wallet. It is open for all who believe the decline of progressive and libertarian values have set us back as a democratic nation.
For more information on how to handle quotes, please go to How To Quote Sources.
makes it easy to create links to other sites. Now pay attention because there are two parts to using this button.
. You need to put the internet address (URL) to the place you are linking to after the backward slashes [ // ] and right up to the quotation mark with closing bracket [ "> ]. Normally I prefer people use the title of the article or page they are pointing to; but you can use text like "Source", "Here", "Link", etc.
button again to insert , the link that closes your code. So culturekitchen looks like this : culturekitchen.
is used to insert the <"!--break--"> PHP tag (without the quote marks) to divide the content that will go the front page from the rest of the post.
