According to: http://soylentnews.org/comments.pl?sid=5037:
"We're adding standard support for sub/sup/abbr/strike tags. We're also adding support for the custom tags sarc/sarcasm and two forms of a "user" tag."
Let's submit a story with each of these in it:
SUB: thissubthat
SUP: thissupthat
ABBR: thisabbrthat
STRIKE: thisstrikemethat
SARC: this<sarcasm>that</sarcasm>and the other thing
SARCASM: this<sarcasm>that</sarcasm>and the other thing
Submitted as "Plain Old Text"
Looked okay in submit story preview window... now clicking "SubmitStory".
=====
Looked correct when I first loaded the submission to review for acceptance to the main page... NOTE: the above ABBR tag had a single word as its title attribute value and made it through, correctly, to the first display of the submitted story.
Pressing "preview" button in story submission review screen:
Now, on the "Previewed" page:
1.) The ABBR phrase was deleted.
2.) The STRIKE phrase was also deleted. (https://dev.soylentnews.org/submit.pl?op=viewsub&subid=1176&title=new+tag+support+-+sub%2Fsup%2Fabbr%2Fstrike+tags)
