Don't know if this has been noted or not (I skimmed 13 pages, but found nothing). When you post a reply/new post within the iPhone app and use the "&" symbol... the rest of your post gets deleted. ALSO, I'd say that it's a 20% failure rate of posting from the iPhone app in general. You get finished a nice long one, and presto! It's no where to be found. Doesn't post and disappears into cyber-space. It's gotten to the point that I either cross my fingers or 'copy' the post just in case.
I've heard others talk about it various threads on the site itself, but thought I'd mention it here. Seems like it should be an easy fix.
Other than that, great app. Looking forward to update changes.
