About: my goal with Fire was to combine all the best ideas, features, and strengths from the IppoLit family of releases...IppoLit, RobboLito, Igorrit, and IvanHoe. in addition i have added all the best ideas that Sentinel and i came up with during the development of Robbolito 0.085g3. with enormous beta testing help from the Decembrists and Robbolito comrades, we posted more than a dozen public betas on Immortal223 during the last four months of 2009 (for details, please see the RobboLito page)
