How to delete past "new topics"

[Kaisgraham]

from "my chow"?

[Jacquilynne]

Are you referring to the default 'my posts' section of 'my chow'? That's based on which threads you've participated in. They'll gradually fall off once you reach the maximum of 72 and they get replaced by newer items, but otherwise, it's automatically generated and you can't remove items.
