Good to see you here, Lynn!
Both
Sudoku Solver (by Richard Broughton) and
JSudoku (by Jean-Christophe) will handle Clueless Specials and Clueless Explosions. I use them all the time to calculate pencil marks for me, and to print entire puzzles (I print the individual grids with Sudocue, but that may change soon, as well). Not only that, but Børge posts a new one of each for us each week, usually in several difficulty levels.
He and tarek have been taking turns posting a weekly samurai, and tarek also posted several nice Kazaguruma a couple of weeks ago. In addition, Jean-Christophe and others post puzzles for us from time to time, as well. And of course, the killer and kakuro sections are always active. (I'm wondering how long it will be before someone comes along and posts a new taiken, MOAG, or DOAG, but I expect it's not too far away.)
BTW, you SHOULD be able to delete your own duplicate post/thread. If it doesn't work, try PMing Richard Broughton (administrator).
