To cover all the bases, there's a lot of possible variations of profanity censored, one of which resulted in "flicking" being censored. (funny, "flick" would have been fine, but "flick
ing" was censored

)
Anyway, it's fixed now.
About the aiming, you said, "Now I'm aiming juuuust before the ball is released in the toss". Try aiming even sooner to hit even closer to the lines. That, essentially is the difference between my first and second serves - the sooner you aim, the closer you can get to the lines, but it's a bit more sensitive and is easier to hit it out.
If you go back to the TopSpin School, you'll see the part about aiming early. Actually, pretty much everything you need to know about serving is in there.
