You could copy the layout file corresponding to your documentclass, modify that changing your fontsize etc., possibly introduce a new section and map it to the appropriate latexname, and use that as your layout. This is quite simple and the learning curve should take you a couple of days at most.
Before you do this, check to see if your document class provides support for acknowledgements, directly or indirectly. With the layout file approach you might be able to create an Acknowledgements section which is a combination of a section with custom formatting info (like heading level, style, etc.) which. One of the lyx help manuals (Customization?) documents this procedure very well. -- Manoj On Sunday 21 February 2010 12:09:14 pm Sajjad wrote: > Hello forum, > > I am about to finish my thesis work and i am stuck with some issues in LyX. > > One of them is writing Acknowledgement section. > > I see that there is no separate environment for this. > > > I would like to have Acknowledgement right after Abstract and like to have > the same font size as "Abstract" heading and centralized. > > > Any hint? > > > Regards > Sajjad
