Hi CATEGORIZATION.ORG I have feeling this domain may be worth more than Reg fee. 1) Categorization (with the "z") is the more popular dictionary/Wikipedia word ( 8 Million Google results http://www.google.com/search?hl=en&q=categorization ) than Categorisation (with the "s" Almost4 Million Google results http://www.google.com/search?hl=en&lr=&q=categorisation&btnG=Search ) Wordtracker 5 search a day http://www.digitalpoint.com/tools/suggestion/?keywords=categorization&country=us 2) Even though .com most of time is better than .org, in this instance I think Categorization.org is more valuable than Categorization.com 'cos Categorization is related to Organization (.org) and useful for many corporate/commerical development. Ok, so we all think our domains are always great so any appraisal/2nd opinion would be much appreciated. Cheer!
