Please ignore any email you receive that looks like this, it is spam.
I've just received an email, apparently sent by admin@gwulo.com, titled:
david@gwulo.com EMAIL VERIFICATION
I get a lot of generic spam like this, but this one has a very believable message:
Hello david,
please validate your david@gwulo.com address
as we are going through new server upgrade
Below it is a button, CLICK HERE TO VALIDATE, that no doubt will start some attack on you.
Please delete the email immediately.
