Here's a copy of an email request I've just sent to a few LW people I know:

One of the rooms in Conway Hall on Sat 24th April will be set aside for posters and general socialising.

The posters are opportunities for people to publicise various activities or ideas. We've received half a dozen applications for posters so far, and we have room for one or two more.

We expect that many of the attendees will mingle in this room at lunchtime, during the afternoon break, and (for early birds) before the formal start of activities in the main hall at 9.45am.

Would one of you be interested in creating and displaying a poster about Less Wrong / Overcoming Bias?

Many of the attendees to the H+UK event will have little prior knowledge about Less Wrong, so it's a good chance to reach out to potential new supporters.

Posters can be a number of sheets of paper, stuck onto the wall with bluetack or sellotape. Maximise size in total allowed per poster is A0. Several of the posters will be A1, made up of 4 A3 sheets.

If you are interested in this, please let me know, since we have to control overall numbers of posters.

To be clear, there's no charge for this - consider it as an opportunity for free advertising :-) You're also welcome to bring small pieces of printed literature for interested people to take away.
