committer. Simon has been quite active on the user mailing list helping answer 
community questions, he also maintains a C# port of the lucene-hunspell project 
(java: http://code.google.com/p/lucene-hunspell/, Simons c# port: 
https://github.com/sisve/Lucene.Net.Analysis.Hunspell) which is commonly used 
for spell checking (but has a wide array of purposes. Please join me in
