Back in the day (~2004) I was an avid RTC player and GG had just released a version of RTC with a visual editor. Then my PC crashed and I decided to get a Macintosh laptop. At the time, macs did not support windows opperating system, but of course now the new ones do because of the Intel chip. So I have not been able to play DM for over 5 years! Now I'm done my graduate work at university and I have some money to get a new MacBook Pro, and I'm looking forward to loading up RTC again.
I've browsed the forums off and on over the years but really haven't kept up to date with what's been going on. So basically, I'm wondering if any kind souls out there would be able to summarize briefly the activity of the last half decade!

(Any politics, big development decisions, etc.)
In particular, I'd like to know which custom RTC dungeons I should try tackling. Way back, I had what I considered a great idea for a grand custom RTC dungeon, but never got around to putting it together for the reasons mentioned above. Would love to get back on that in my spare time, give something back to the people who've provided me with hours of DM entertainment.
