Dave, I have not moved everything for templates into a place where it can be easily edited by administrators. However, in creating the basic of the template system I did move 'templates' to the database, such as Email and Delete Posts. Unlike Email, however, Delete posts need to be updated via SQL at this time. All data is stored in the Forum_Templates table. This table contains only the delete post reasons at this time. Ones associated with -1 moduleID are the base which are used to copy over for new module instances. This ultimately allows all forum instances to have their own custom reason templates.

So, if you want to remove a post delete reason you should just delete the module associated instance row out of the Forum_Templates table. If you want to update it, update the TemplateValue table.
