LyX ⇒ Acknowledgements in Lyx

[leonidis]

Dear Lyx Community,
I would like to insert an acknowledgement part at the end of my thesis. There are two problems: First the acknowledgements shall be inserted after the appendix at the very end of the document. Furthermore the acknowledgements should not appear in the table of contents. I tried to circumvent the first problem by inserting the acknowledgements part into the last appendix chapter. But when I make the title "Acknowledgements" also the title "Appendix C" appears.
Thanks a lot for your help,
Markus.
