I'll never make a module which works only with 2.2.x
That's definitively what I wanted to head.
2 more questions : 1/ I wonder how you will manage 2 core as a base for your module from now (with Xoops Cube and Xoops)
2/ why not implementing category management for your feeds. It could be interesting in certain occasion, and better than to use duplicate feature. What do you think about that idea ?
