Dear Steve,
to make it more special why not comment on
our abilitiy to do the hard/soft analysis at forward eta?
For my (non-Brahms) abstract tested it in a simple latex
file and then pasted only the abstract part into the window.
Thus the window contained thing liks $\sqrt{S_{nn}}$ but no
\begin{abstract}.
Yours Michael
