Well, I'm still using the old LJ form and not bothering with novelties. So far so good, but I agree with you - why try to fix it if it ain't broken?! They're probably calling it a "successful" upgrade, but this successful operation will probably end in a dead patient - LJ. :P
Lot's of luck and wonderful things at your London trip and I hear you, being busy, so don't you worry about it - I've made it from work today only to host British guests for an hour and in the evening our Dutch friends came to spend 2 nights at our place - it's ridiculously eventful! :)
Enjoy, babes, both of you!
