Any admin or global mod or forum specific mod will be able to assist at there discretion. However, allowing topics/posts to be deleted that are not as a result of in-compliance of rules (in my opinion) could defeat the purpose of a community where people can learn and share knowledge/experiences.
I don't know your reasons for requesting this but I think it's a good thing seeing someone progress with there animating, we all start somewhere. I know for example when I started web design my first projects in hindsight are cringeworthy - but motivating knowing how far my knowledge/skills have developed.
You could try sending a PM to Jeff (admin) or Azure (global mod), both seem quite active and approachable.
Good luck! :)
