I am new to this forum but am very impressed with all the generated feedback from all the posts. I am starting a webhosting company and am i need of a DNS web based management tool that will allow users to create theur own username and password as well as add, delete, manage their domains. I will be offering this all for free. I have seen such sites as www.generaldns.com that offer this but am unsure what they use. Any help would be appreciated.

Thank you in advance.
