Calimanjaro and Gemx and both looks like they are abandonware.
I agree about Calimanjaro - though he did reduce the price once, so it hadn't been completely abandoned,and can still be bought.
I think it is a bit unkind about GemX. The website, forum etc is a completely new version as is the pricing scheme. Forum is not very active and they don't respond as often as they might to questions (and no response to yours), but they do respond to some - and even put up some images of parts of the version in development (eg the mailer) in answers. So, I don't think it has been abandoned. I wouldn't buy it unless it does what you want now though even with its being the last day of their 2 for 1 sale today.
