Have you ever collaborated with another writer on a project?

I havent as of yet (unless you count my sister and I writing togehter when we were little) BUT my bf and I are planning on writing together which should be interesting...

It's very good to collaborate with another writer on a project. You can share idea's you want to be part of new books you are going to write. You will have half the work but profit for both

i have. i did research for another writing and loved it. i love doing research maybe even more than actual writing. the writer was a friend that i had met through a writing group so i didnt hesitate when he asked me.

Yes i have collaborated with many people on projects ..sometimes it bring th best out of both of us and sometimes it ruins the project due to misunderstanding.With me its always the latter , unless its a good friend of mine..because i like to write free..Work on stuff how i want to..I hate being dominated by work partners.
