A month or so ago we set up an ALPSP group on LinkedIn... and a few weeks later I actually figured out how to confirm people as members of the group (d'uh!).
Since then, the group has grown to 100 and counting! The intention is not really to push much ALPSP specific stuff via LinkedIn - we'll still do that via the e-newseller, ALPSP Alert, this blog and our e-mail discussion lists - but rather to provide another place where members can network...
Of course, if you do spot an interesting publishing related news item then feel free to share it with colleagues in the LinkedIn group, and similarly if you have a topic for discussion that you want to share then go right ahead!
