Thanks people,
My apologies for not explaining what WYSIWYG (pronounced "Whizziwig") meant. I assumed that people who had might have an answer for me would know as they have had to have already selected that setting
To change this option go to "Quick links" on the menu at the top of the page, then choose "edit options", Scroll down to "Message Editor Interface" then select "Enhanced interface - Full WYSIWYG editing"
Among the benefits is the fact that when you cut and paste your poem from word you keep the formatting (so you don't lose and then forget to replace your italics like I always do. Another is that when you want to use white space to align/offset your text you don't have to deal with tags getting in the way and confusing you.
Anyway, I've done some research. There's a long-standing issue (since at least 2010) with neither the Safari or Chrome being compatible with vBulletin WHSIWYG editiors. There may be an extension or patch somewhere (I found one and couldn't install it), but if I find something that works, I'll let you know. And maybe I'll also check Firefox out some more.
Thanks,
Matt
