About this time last year I spoke at a conference organised by Software Developer network in the Netherlands. It was a windows developer conference with the usual asp.net/vb.net/c# tracks, but they'd added a DotNetNuke track as well. The sessions were all really well attended, so this time out they've expanded their coverage and there are now two dotnetnuke tracks with more than 20 sessions over the two days, as well as 80+ other topics. If you're interested in DotNetNuke and can get to Arnhem in mid-September I recommend it.
As well as our first 'official' European conference, we've also having a US based conference - this time with a couple of tracks at the devconnections conference in Las Vegas in November. It's a much larger conference with approximately 4700 expected over the 4 days. The lineup and sessions there are excellent, particularly as theres no PDC this year, and we're hoping to get a good turn-out for the DotNetNuke tracks. Personally I'm just hoping I don't get drawn in the same timeslot as one of the big hitters like Scott Guthrie :) . If anyone makes it to either of the conferences, make sure and track me down for a few beers.
