Forum Blocks Manager "Template to Use" field

[kh99]

Do you mean when you want to actually set the template used by a New Forum Posts block? Then you'd go to Forums & Moderators > Forum Blocks Manager, and when you add or edit a New Forum Posts block you should see a field for template name. But as I mentioned above, you won't see it labled unless you also created the appropriate phrases (and I was too lazy to figure out what they should be named when I wrote that post).

Edit: oh, I see now that you're the one who originally asked the question, and it sounds like you understood this already. So maybe I don't understand the question.
