I don’t have any articles about waist training or tight lacing on the blog (other than this one from about tight lacing myths from Little Miss Risk), but I do know you’re only supposed to do it with a custom made corset (i.e. no tight-lacing off the rack and especially not with cheap corsets) and that if you’re ordering a custom made tightlacing corset, the corsetiere will probably be able to give you advice about how to do it.

For other general corset advice and info, I recommend Staylace or the Corsetry Group on LiveJournal. I wouldn’t be surprised if there’s a forum on tightlacing on more adult-oriented websites, but I can’t remember the name of that one really popular one right now.
