Hi again. This post is to explain all users a little more about this blog.
Firstly, to succesfully agree with another user to trade an item you should use your RuneScape account, can be the original or the new one Jagex added with the player names upgrade.
Also, I want to leave two links for the databases, first one is the Grand Exchange database and the second one is the Zybez item database, so... enjoy 'em.
