My webapps question seems to have disappeared, I'm assuming it was deleted? It would be nice to be able to see this information somewhere, how can I learn what if anything I've done wrong if I get no feedback?
--added after ChrisF's helpful answer--
not constructive is defined as:
This question is not a good fit to our Q&A format. We expect answers to generally involve facts, references, or specific expertise; this question will likely solicit opinion, debate, arguments, polling, or extended discussion.
I don't really see how this fits, seemed pretty straightforward to me. Unless there is some confusion as to what defines a "major" email provider? Then I could have been requested to reword my question.
