For a very, very young and small port (March #'s, month 2 overall, trending is recent performance)
SS - 1 Declining (even with daily uploading, first goose egg ever yesterday)
IS - 0.16 Strong growth
DT - 0.14 Moderate/Strong growth
FT - 0.12 Flatlining. Adding images does nothing
BigStock - 0.04 Growing
Can't get in to StockXpert, no sales yet at 123RF, port too small to yet bother with the little sites.
