on deviantArt you can simply use HTML to format your postings, that means, when you want to start bolding your text, you write <b> and when you want to stop bolding again, you write </b> .. this goes for all the other tags too:

<b>: bold
<i>: italic
<u>: underline

<ul>, <li>:

• ul and li

are used for lists, like points you want to complete - each <li>your text</li> will become a point on its own.

<ol>, <li>:

1. ol and
2. li

are used for ordered lists, if you feel like numbering something - each <li>your text</li> will become a point on its own.

<sup>: ^{superscript (sup)} (like in 1^st)
<sub>: _{subscript (sub)} (the opposite)
<code> and <tt>: would cause all the characters to have exactly the same width
<acronym>: welcome to <acronym title="deviantArt">DA</acronym> would become "welcome to DA"
<em>: em and (to emphasize)
<strong>: strong tags (to print things in a strong way)
<abbr>: "don't use <abbr title="abbreviations">abbr.</abbr>" would become "don't use abbr."

<a href="some link" title="mouse-over-description">Text</a>: Text hyperlinks: these are those little texts you can click to get to a different page (the title="description" you can put there if you like, but you don't have to. it would be displayed if someone hovers the link with the mouse)

Also, you can use &nbsp; for a forced space - a space that will displayed in any case (usually if you put two or more spaces behind each other, only one will be displayed)

Even if it's not really intended for, you can indent text by writing <ul>Your text</ul>.

If you are unsure - try sending what you want to write in a note to yourself, so you can see how it would look like .. alternatively, you can also go here n.n

Subscribers may use the following tags in their journal as well:

<img src="http://url_to_picture.jpg" alt="description" />: to include images in their journal (they must be hosted on a different server, not on deviantArt). The description you put there will be displayed if the image cannot be loaded for whatever reason. Note that you have to be a subscriber - if you need a place to put your image, try imageshack! ^^

Subscribers can type <div align="center">Your Text</div> and <div align="right">Your Text</div> to center or to right-align their text on their journals. This works for all the text and the images (basically everything) that's after the first "div" tag and the closing "</div>" tag, after which it will be left-aligned again.

<cut>any text you want</cut>: this will "cut out" the text on your journal .. if someone reads your journal on your deviantPage, they'll see a link with "read more" instead of the cut out text, which they can click to view your full journal. it's a good way to keep your journal all tidy on your deviantPage.

<strike>text to strike through</strike>: this will make a text appear striked through

if you need information of how to easily link other deviants, include their avatars or even thumbnails (subscriber's journal only) in your journals, posts and other comments, have a look here.

If you would like to test how a certain formatting or journal entry would look like, feel free to do so here.
