Can I get free GA kits somewhere, can I export my own?

First of all, excuse me if this information is somewhere else and/or if this is very obvious stuff.

  1. Can I download kits / patterns for GA SE4 somewhere on the net for free or otherwise? or does GA SE4 library only work with officially released patches?

  2. Can I share my own kits and pattern banks? if so how do I do this? Do I need the full version of GA to do this?

Yes, you can import and export non-Steinberg content. To export, just right click the kit to the top right.
