got loads stuff in my stuff i no longer want how do i delete .. items.. i used to do it but cant remember how i know it wasnt in trade or store

What do you mean it wasn't in trade or store? Are you referring to free items that can't be traded or sold? If you can't sell or trade them and want to get rid of them, you can go to your inventory crate and search for them. You can then remove them from your inventory.

its all items in my staff got loads in there i no longer want weres my crate to delete tytyty i found it

The inventory crate icon next to the clothing icon on the bottom is where you can view all your stuff. Both in use and available. Click whichever one of those applies and then search the item name.
