The best (re: most reliable) method is via email. You can email Renee any time at Renee [DOT] Elizabeths [AT] gmail [DOT] com.
Also, if you have a question for the other contributors to this blog, they all have their own email addresses.
The Muse: Reneesmuse [AT] gmail [DOT] com
The Inner Editor: Reneesinnereditor[AT] gmail [DOT] com
The Idea Salesman: Reneesideasalesman [AT] gmail [DOT] com
The Project Manager: Reneesprojectmanager [AT] gmail [DOT] com
(Yes, you can email the voices in my head. Yes, they will respond. We're running a full-service crazy station around here.)
Renee can also be found a few other places around the web.
The Idea Salesman has been lobbying for the abstracts to have their own Twitter account, but thus far Renee has resisted giving in. She spends enough time talking to herself as it is.
