It might come in handy for people to know some basic HTML tags, so that we can all format text and links and such. So here's a quick rundown.
HTML is the code that tells web browsers how the text and images on a page will be laid out. Most tags have an opening and closing tag, affecting any text inbetween them:
<tag>text</tag>
The / in the tag means that you're closing whatever effect you're using. Some tags, like the tag for inserting an image, have no closing tag.
Here are some basic formatting tags:
<b>bold</b>
<i>italic</i>
<blockquote></blockquote> indents an entire paragraph or passage.
Link tag:
<a href="http://www.whatever.com">some text</a>
That will look like this: some text
Image insert:
<img src="image_filename.jpg">
This one has no closing tag. Also, it can exist in the same post as text; you don't have to comment on your own image to label it.
