This is a question from a user, which was resolved via email (and software patch):

Hello, I have met a question with using voson now.
I'd like to collect hyperlink sites through voson, and I have created a new voson database, then pressed the "add seed sites" button. But there wasn't any reaction. I couldn't see the "add seed sites" window. However, Last year when I used voson there was no such a question. What has happened to my account? Is it all because of my free account? If I upgrate my account to profession will the problem be solved? I look forward to your reply! Thank you very much!!
