Nice comforting editorial today Steve, thanks. It's certainly how I've made whatever name I have, more as a developer than a DBA but it's the same principle. I've learned and forgotten more stuff than I can remember (that's why I've forgotten it!) but if I need to know it I'll work it out.

I'd comment that muddling through seems a peculiarly British idiom, perhaps I'm wrong, or perhaps you have been lingually influenced by visits to this side of the pond? 🙂
