Absent Founder

The founder of a site I work on left, and he left the site to me. He's made it clear he does not plan on returning, and now my members are wondering if there is a way I can assume the position of Founder, since many fear that he may delete the forum, or doing something to sabotage it.

I have PMed Typlo about the issue, and until I get a reply I thought I could ask for solutions here as well.

What can I do?

You cannot do anything. One way is he gives you the account details.

Typlo, won't give founder access to anyone until the original founder is found to be inactive on the forum for last 6 months.
