I am interested in port some of dexterity games, for instance, Dweep Gold, to the mophun platform, which is a game console engine for mobile phones. However, the guys of mophun.com told me I must get consent from the intelligence right owner of the ported game to avoid legal problems. Who can let me know the contact infomation, eg. email address? Thanks in advance!

Here's our contact info page:

Just use the vendor contact link on that page.

Steve, do you have any plans for licensing Dexterity's games for handheld platforms? I am sure many of them will do very well in that market.

Yes, but most likely we'll work on Mac ports first.
