Since the revamp of the site many of my links to LCD tutorials no longer work.
I look for part one of the tutorial om creating context sensitive lists and it's no longer there.

Part 2 is but not 1!

Also there was a LCD e-seminar back in November that has not been made available as part of the on-demand service and is no longer listed on the site.
I'm pretty sure this is just a transitional thing to the new site design. They are likely furiously working on completing the transfer of resources, but there are a huge number of items so it's probably just a matter of time. You can always contact team [at] acrobatusers [dot] com to let them know about missing items from the old site.Hope this helps,
