because of your question I went to check all modules available at MODLAND stored under any of his aliases and visited the Crusaders homepage
, too. Your guess is correct, both are the same person. However I did not find any trails of the nicks Dr. Cool, Dr. Cruel, Son-Ja nor of the group Frogs. So I do not know where Jason would have used those aliases. MODLAND had him listed by three different aliases which I now corrected, so thank you for questioning this in the first place.
