You have probably noticed that the Pearson 422 owners web site http://www.pearson422.com is no longer operative. A couple of us are trying to find out exactly what is going on but have been unsuccessful so far. In the meantime, the site's discussion forum (that I host on an old machine in my office) is still happily chugging along, although it has not seen much activity since the website went down. The forum can be accessed through the link below. I will keep it up to date about what is happening with the 422 site. Regards, Derek
