There's a time window on edits out of security reasons. You can edit your post for 3,5 hours after your initial post. After that only a mod or admin can edit it.
I can mark this one [CLOSED] and you could start a new thread or edit out the "... for Spirit " and you could state what you're looking for in a new post in this thread. It would be fine either way. We're not big in formalities.
You can even have more than one for trade thread.
Just remember to post a price even in trades so people know what value items they can offer you.
You can PM me if you have any more questions too.
