There wouldn't be any security problem, Janie, nothing is stored, it would be deleted as soon as I read it. But anyway, no problems. For true flavour you're going to have to go with heirlooms and you'll probably only find them with online seed suppliers. Here are a couple of recommendations for you to look for:
Marianna's Peace - as I said, a tomato great. Large dark pink beefsteak on a potato leaf plant. Like a glass of fine red wine.
Cherokee Purple - it's mentioned on the blog. Its sister, Cherokee Chocolate, also on the blog, isn't far behind. Doesn't have quite the same intensity of flavour.
Brandywine OTV - another dark pink befsteak on a potato leaf plant. The result of an accidental cross between a Brandywine and an unknown yellow tom, grown out and stabilised by a couple of American growers. More productive and less temperamental than Brandywine and a delicious tom.
Soldacki - a Polish variety, yet another dark pink beefsteak on a PL plant. Beautiful tom.
Best of luck!
