My experience with SPICE goes back to the late 70s, though I have limited recollection of that. I was a big user of SPICE in the late 80s and have continued since. I became aware of LTspice in the mid 00s, and have become a convert. I feel it is important to "give back" to the user community and give advice when it's needed.
The LTwiki is my "go-to" source for "undocumented" information about LTspice features that are either not in, or not described well in, the Help that comes with LTspice.
