6/5/11 UPDATE: I am expecting to be able to release an alpha version of the Monster Builder and Encounter Builder component in roughly 4 weeks. At this time, you should be able to import monsters and traps from 4EParser files, from a copy/paste from the Compendium entry, create new monsters and traps, and build encounters from your local database of monsters and traps. Export of the encounters, monsters, and traps will initially be to HTML.
I recently posted a question on the Ask a DM forum, looking for a lightweight kingdom management mechanic to incorporate into my campaign. Something functional, related, and doesn't overwhelm the campaign.
