Campaign Plans/Description

I thought I'd do a meta-note on this campaign especially for blog readers who aren't players in this campaign.
The Loudwater Campaign is a 4e Dungeons & Dragons Forgotten Realms campaign centred around the town of Loudwater and the Gray Vale. The campaign started in April 2011 at level 1. It is intended to go level 1 to level 30 over roughly 5.5 years, April 2011 to around August/September 2016. We play fortnightly at the London D&D Meetup. There is a single party XP tally for all PCs, the group tends to level up about every 2 months, or 4-5 sessions, each of ca 3 hours, so about 12-15 hours of play. This is roughly 6 encounters, but can be as little as 4 major encounters. Progression has thus been about 6 levels per year, and is expected to be roughly 6 levels/year:

April 2011: level 1 - start (irregular)
January 2012: level 4 - session 11
January 2013: level 10 - session 33
January 2014: level 16 - session 58
January 2015: level 22 (no session Jan 2015, session 80 Feb 2015)
January 2016: level 27?
July 2016: level 30?
