I am sorry; I did not delete your question intentionally.  If I did it accidentally, then you have my profound apologies.
The situation was this: another user had left a question which overlapped with the Teahouse headings, so I edited the whole page (normally I would just edit one section at a time). When I went to save my changes, there was an edit conflict - that was probably you asking your question. I thought I had recovered all the input, but perhaps I missed yours in the conflicting changes.
I see that you asked your question again, which is great - the Teahouse is a tremendous resource which has helped me a lot and I hope I didn't put you off using it.  Did you get the answers you needed?  If not, I can help with those ones.
