Who can I contact to get a thread deleted? There is no contact email or anything else to contact someone at DP.
Information regarding thread deletion is found in the Help section. The link is found at the bottom right hand corner of this page. The particular section regarding thread deletion is found under the policy link https://www.digitalpoint.com/help/policies.
Considering this is the only thread you have here, I'd say your chances are zero. You definitely can't delete threads by other users if that's what you are trying to do.
