I don't know if you guys have as much trouble staying organized as I do, but I was constantly having to dig through emails and folders every time anyone asked me a question about a patch, tech spec, etc regarding OTM. You may already have this, but I keep these 2 links bookmarked so I can have easy access to the OTM documentation and it has saved me quite a bit of time. I like how they list the patch notes as well.
