How interesting
No matter the circumstances, welcome back, Liko. You have been missed.
Just one thing - did you copy
any code from TBA? I mean, this is kind of a big deal in the mud community. Actually, the rules for creating a derivative work are quite strict. If you, at any point, had the tbamud code and your new code available on the same PC and they can read the same file formats, they may be considered a derivative work. Wikipedia has more on the practice
en.wikipedia.org/wiki/Clean_room_design
while there's a lot (seriously, spades) of noise about it on the old circlemud mailing list.
@Fizban - whether the license applies here depends on the answer to the above question.
