If you want LUA, get it from BCDC++.
DCDM has lua support because it was based on an old version of BCDC++.
As for the Script Editor, psf8500 made for it . . . . good luck updating that to a newer WTL.
DCDM++ svn hasn't really been worked on for ages, because the dc++ version it's based on is way too old now, so i would agree, it's kind of dead meat. But very tasty meat, full of plunderable features, if you wanna go the copy / paste route. :)
