Form is here: http://momondays.com/speak/request-speaking-slot/
This form has a ton of routing set up depending on the city selected by the user. Generally, it works well - but now and then either 1) a user submits a form and goes to our 'Thanks for submitting...' confirmation page, but the form does not show up in the entries (and no notifications are sent) or 2) the form submits, but not all of the notifications go out (each choice of city routes to at least 2 admins, plus the user).
I suspected an Internet Explorer conflict, but I tried in IE and it seems to work. Are there any known issues on this end that would cause either the form to not submit at all, or notifications not to go out?
