I have been away from LDing for a long time mostly due to poor health. Now I coming back to it. What new techniques have come out since I have been away? The most recent new technique I can remember that made any impression on the LDing community was SSILD. Anything else since then?
Same! 
People are always coming out with new stuff.
i would suggest looking in Lucid Lab (ld4all.com/forum/viewforum.php?f=44)
other than that
there’s not much i can do
hope this helps
