I'm currently playing in a 4e campaign which is based on a converted Kingmaker campaign. I'm also running a 4e home brewed campaign, in which I'm testing out a lot of 4e hacks. And until about 3 months ago I was playing in a second 4e campaign using the Neverwinter Campaign Setting. That one ended at it's natural conclusion.
I have not used any of the DnD Insider tools since they went completely online, and only kept my subscription for the Dragon and Dungeon Magazines. I still use the offline character builder, and the offline monster builder as electronic tool alternatives.
