Here's a link to the Daily Kos FAQ. Read it, learn it, use it.
Here's a link to the section in question: Writing Diaries
#24 is the pertinent part:
Do not use ALL CAPS or exclamation marks !!! in diary titles.
More ranting below the fold....
After a diary has been posted, its text can be edited. To edit a diary, click on the 'Edit diary' link just underneath the title. The page that appears is similar to the New Diary screen, except that the existing text of the diary has already been filled in. Make the desired edits, click Preview to check that everything is displaying correctly, and then click the 'Update' button to change the text. Note that editing a diary results in that diary's timestamp being changed. If a diary is edited on a day different than when initially written, that edit counts as that diarist's once a day diary.
You'll need to know how to do that if you've insisted on using All Caps in your diary title and are lambasted by the Diary Police in your comment section. All Caps = Screaming at the top of your lungs. Not cool. And not necessary.
While we're here, I may as well bring up another pet peeve of mine - Tags. Specifically, using commas to separate them.
Handily enough, that little tidbit of information is staring right at you when you're adding tags to your spiffy new diary entry:
Add keywords that describe your story. Separate multiple keywords with commas.
Simple enough, eh? Keeping the Tags corralled is a difficult enough task without compounding it by having a series of 20-word tags added into the mix because of a lack of comma sense. (yes, I meant "comma sense" - funny, yes? No? Fine, be that way. <sniff>)
So, in conclusion, please -- Read. The. FAQ.
The Diary Police - and their facsimiles - will be watching.
P.S. Add any other helpful links in the comments section. I know they're out there.
