many Xmas seasons ago, I was new to the SX and was proddiing and pleading to get a manual or tutorial...
I even wrote the famous Xmas ditty:
"O Come, O Come the manual"...
a big hit, but it produced no results...
there was talk of a video tutorial (several times) but nothing ever developed...
after 5 or 6 years of having the SX (two of them), I'm still figuring out the routing and how certain functions work...
the old forum was extremely helpful and you could search the threads for almost every question you had...
if there was no answer in the threads, there were 35 or so very active members who could answer all your questions...
even the actual people who designed the SX were on the forum...
by the time I came on in 2006 or so, the SX forum had wound down a bit, but there were still plenty of active users...
so, to answer your question, I don't believe a tutorial will ever be written/made...
but, hang in there, you'll get the hang of it after awhile...
if I could figure most of it out, ANYONE can!!!
