Onzin† - its the just for fun forum, so its hard to go wrong there.
If you want to play it even safer, the Verjaardag-forum† is for birthday messages.
Then when you graduate from those there are buiten-A-ards and the fly-by-room. And once you get out of those you should have a fairly decent understanding of Dutch - I rarely use the translator now and even though my grammer is wrong, they know what I'm saying.
*And on aside note, my translator turns peter1963 into godfather - it took me a long while to figure out why there was all this talk about godfather's here.
