Hi,
I just thought I would check out Rick Morneau's machine translation interlingua to see what else he has done with it since I last studied it. But sadly, it does not appear to have been updated since October 06, 2006. =( Still, of all the rationally-designed conlangs I had seen on the internet, this one looked the best by far, so I am very glad that what reference materials there are of it are still online, and that the lexical semantics in particular is as comprehensive and thoroughly thought out as it clearly is.
