and I'm just getting back into Subeta.

I seem to remember something where you give something and get something else in return, of the same value - more or less.

but I can't seem to find it. does anyone know what it's called? Gift exchange, maybe?

You mean the gift exchange? It is still around. I wouldn't count on getting a desirable item from there though as not many people use it.

thanks! I just like the surprise of random items.

any tips?

If you like getting random items, you should try vending :D Here is a little guide if you are not familiar. Unlike the gift exchange, it is not dependent on other people donating gifts.
