I get a lot of feedback from people that they have a hard time finding out about various tech events in Ireland & Northern Ireland. For Microsoft developers, we have mtug.ie, dublinalt.net, microsoft.ie and a variety of other sources for tech events news.
So I put together a Twitter alias for Microsoft tech events. You can follow us at http://twitter.com/MSIrlTechEvents to stay up to date with events, training and other announcements. Hope that helps!
