Same here... not seeing Turbo directly. :(
I'm using GMail, and don't see his messages in SPAM, either. Only rarely, does a CRTech user's post end up in SPAM, and I always click "NOT SPAM" to "teach" the system to let them through.
I do get a number of "warnings" from a handful of "regulars" saying that their e-mail MAY NOT have originated from a GMail account (bla bla) and I always click to "create filter" and "never send to spam" on them... repeatedly. Apparently, GMail isn't "learning" those. :( At least they DO get through, tho!!
