In the answer's box but I'm not sure you can as a Guest. Only alternative would be what you have done citing the original quesiton

Usually, for people who aren't guests, you put the thanks under your original question - but as a guest, you don't have that option, so you've no choice but to post another "question" saying thanks to whoever.

You could always thank people in advance i suppose. ;)

Not quite the same, though, is it Windy!

Thank you all,

Welcome to GoY, Daffa...

Thanks for the advice on my Libertia to whoever sent it. June

Thank you all for the quick replies to my question; fingers crossed! Bridgette Hunt
