NetSol is a problem trying to look like a solution. When they were the only registrar I could find, I used them. As soon as I learned about Joker I switched, even though it meant sending a fax from the US to Dusseldorf, because it was still cheaper and a far better experience.
Every time I encounter someone using NetSol, I have pity for them. That Marketo uses them says things. None of them complimentary.
Hover includes an anon layer free, so no more fake renewal letters in the mail. While I do check in during the renewal process, it has always worked. It's almost too easy.
