Well as it ispedants' corner maybe an apostrophe somewhere might be apposite, (I'm), adjectives are not usually written with a capital letter and , as you say, vicious/viscous(?) leaves one . Were it not pedants' corner, of course I should have remained silent.
Right, we've heard back from our technical people now. Looks like it's just a change in format that had to be implemented - doesn't affect your posting or the visibility of your posts or profiles. In short - it won't actually affect anything, except that one little box when you post. And even then, you'll be the only one that sees it.
