Hi.
First of all Mark, by posting condescending messages like the one you just did in this thread (
community.getk2.org/xn/detail/3536014:Comment:289381 ), you will not get people to help you any faster (especially since you did not bother to read the whole thread and see that the question had actually been answered).
As far as your questions is concerned, the reason you are not getting many answers is that:
1. This is a volunteer's forum for a free software... sometimes we do not have time to respond to everything (especially when it's been somewhat covered in other posts)
2. K2 2.5 (the only one supporting J!1.6) is still in beta. When it comes out, I'm sure that there will be documentation on how to migrate from J!1.5 w/ K2 to J!1.6 w/ K2
3. Use the technique outlined in this post (except that you will want to upgrade your J!1.5/K2 to K2 2.5 beta before starting the exporting steps)
