i think i would update from dtp to dtpo, because i like to archive my mail with it.
but what i really want is dtp(o) 2 with more databases open at the same time, a more convenient interface and stringent import functions.
to be honest: i wouldn’t like to see the upgrade-path »dtp - dtpo - dtp 2« much more expensive than »dtp - dtp 2«.
i’m quite sure you have a pricing plan for your products ready. please let us know.
