K. Would still like more input from other members, but here is what I can do...
- Update my SE G&FH profile information (so I look like a real person ;) √ done
- Print out a flyer and post it places at the conference.
- Talk up the community whenever it makes sense to do so.
- Tweet the conference.
- Mention hot conference topics/findings in "chat".
- Create some meta questions as per @Duncan's suggestions.
- Coordinate a physical meet up of those attending.
