I don't, but I'd like to say song writing is rather "personal".
Such that if you would like to make it big, submitting to a reputable record company, then I'd suggest you guys not to share it among other people. For its "copyright".
Then, of course, you can share about anything.. like where to get inspirations, how to choose the right word etc, but never, showcase everything.
Hmm, just my 2 cents.
