Sorry to report but both Titti and Davidtack (and all of those you're addressing) are no longer active on this site. They're not regulars here so it's unknown whether or not they'll be back. We can only hope they're OK. Their last replies were 4.5 yrs to 6 ago. You'll note their time/datestamps.
Edgar is a regular and he's still around, bless his heart.
