I went to post in the thread about churches defying the ban on political activity, and found that everywhere I posted "501 ( c ) ( 3 )" without the extra spaces, it turned the parentheses plus 'c' into the copyright symbol. I tried the '['code']' option, but that wasn't appropriate. And turning off smilies didn't help.
Is there a work-around for this, and is there a list of such character sequences somewhere?
