Some things you might want to know about:
September 1 is the deadline if you’re planning to sign up to participate in the annual IFComp. The comp has a new organizer this year, and a snazzy new website. Also, if you don’t plan to participate but would like to donate prizes, you can do that too.
September 13 at the Boston Festival of Indie Games, the People’s Republic of IF is hosting two events: a reading of Lynnea Glasser’s comp- and XYZZY-winning Coloratura, followed by an interactive fiction tutorial covering Inform 7 and Twine.
Also Sept 13 on ifMUD, at noon Pacific/3 Eastern/8 British time, there will be a discussion on IF and audience: how authors adjust their work for a particular audience assumptions made, etc. In the past the IF community has talked a lot about adjusting games for beginner players or for children, and somewhat less (but still a bit) about writing accessible games for visually impaired players — but there are a wide range of possible audience considerations to discuss.
October 11-12 at GeekGirlCon in Seattle, Jacqueline Lott is running an IF intro tutorial in Twine and Inform 7.
More distant, but worth knowing about in case you want to plan ahead:
I myself will not be there; instead I will be speaking at ICIDS in Singapore, November 3-6, where I will talk about lessons from Versu. I will likely also be running a short workshop in IF creation. More about those things when the schedule is nailed down a bit.
