There is a time to say thankyou
-for your patience when the grammar wasn't as it should be
-for your always fiendly informal character
-for your heartfelt laughter when you'd rather be crying
-that every new member was always made welcome

A first attempt

Thank you for your quickly answering.

One question only:
thankyou or thank you?
Are both versions possible?

ooops, thank you
:)

thanks a lot.
