I know there is a way around this, but I can't remember how to do it. Can anyone help please? :)

You can hover over the tree of someone and copy the adress ... so I copied the adress of your tree:

http://subeta.net/users/PUNK?act=gift&usern=PUNK

and now you have to change your name to the name of the person who you would like to gift ^_^

- that's great, thank you :D
