Though your points might be right I would suggest you all use a friendlier tone.
Maybe mails starting with appreciation for what has been done so far, or expressing the strong wish to purchase the software without using harsh words have a better chance of beeing answered.
I'm not talking about kissing someones ass, I'm talking about realizeing who wants something from whome.
No matter how frustrating the situation might be, never forget that here in Amigaland the users are hardly in a position to demand anything from anyone be it software or hardware.
Be happy about the things that get released when they get released and get over the things that do not get released (BoXeR anyone ?). If you can not live with that better turn your back on the Amiga hobby.
