Technically the copyright on patterns prevents sharing and I suspect trading is included since you could have made the pattern and then giving it someone else is the same as sharing.
We do have designers on this site as well as ones who occasionally check it so it's not recommended to talk about sharing a copyrighted pattern on a public website. Both KH and you could get into trouble.
Josette, putting your email in a public forum is not wise. We have spambots trolling the forum all the time and they grab email addresses and add you to the list for spamming. Ick.
