How do I limit the available site templates with a My Sites site? I want to limit our My Sites users to using only a few templates. I mean literally "HOW?". I've googled this and stared at snips of code that presumes the reader has a clue on what to do with it, but no actual statement such as "save this as foo.ps and run it" etc. There seems to be no way to do this from Central Admin. This seems like something that should be right there on an admin page, check the boxes for the templates you want to expose? But nooooo.... (okay, I'm really exasperated, apologies to all).
Somebody got a "do this this and this" recipe for how to limit site templates for My Sites users?
