If you have working email, email "support [at] qso [dot] email". It might surprise you, but I work with email a lot, so please prefer this when possible.
When email is not possible (such as if you don't have an account yet, or are having technical issues), you may also call (USA) '(508)_318_5317'.
Either way, I'll get back to you shortly. If you email from a non qso.email account, remember to check your spam box for replies. Google, Microsoft, and Yahoo are particularly malicious about canning email from small email senders like us.
