Be aware of these conventions, even if you choose to ignore them.
When you write here, it is a common practice to use the second or third person. Remember
Dragnet and write "Just the facts, ma'am." Give concrete advice.
When you
do write in the first person, it is conventional to sign your work. To sign a section of a page, follow it with your name made into a
Wiki Word.
Some wikis prefer all signatures to go in a separate
Wiki Group. If you are unsure, see what others have done.
People often use the first person to describe their own experiences.
It is conventional not to change a paragraph that someone else has signed, except to correct obvious mistakes. So if you'd prefer that something you write not be changed, sign it.
Unsigned work is considered open for change. So if you want to, go ahead and change it.
Practice understatement. Use plain language. Be bold and be nice.
