I submitted a dozen over the weekend and one today but got no automatic email confirmation. Is it only me or is it actually broken?

I asked support via email and they said they see no reports, but haven't heard since if it's actually broken or not.

The bug form seems to have gone down over the weekend. Sorry! We're working on it and it should be back up soon.
In the meantime, you can still e-mail your bug or rfe to support@sidefx.com and if you're on our annual upgrade plan, you can still submit them directly into our database.
Thanks!

No worries. Does this also mean that all my submissions were lost? I don't remember all of them but I will try to submit them when it's back up. Thanks for the heads up.
