No, it's not perfect. I found an online <a href="http://www.spellcheck.net/">spell checker</a> for those wanting one. Unlike IE, you can't find a freeware program to add this feature to Opera's browser. I tried to customize the toolbar to add a button for this link but couldn't do it right. So, save the link as a bookmark, and open it in another page or window. Then you can type what you want into it (checks up to 5000 characters at a time), check the spelling, then paste it in the post window. Nice if you're typing a long reply.
