[NTG-context] Vertical align in side by side paragraphs

Hello, How can I make both/all columns in a paragraphs environment align flush bottom, e.g. for addressing a letter? I saw a line in the manual about using top=\vfill but I couldn’t get this to work. Should I be using TABLE here? Thanks (again), Tom \starttext \defineparagraphs[Par] [n=2, before={\blank}, after={\blank}] \setupparagraphs[Par][1] [align=flushleft] \setupparagraphs[Par][2] [align=flushright] \startPar \vfill % I hoped this would push bob’s address down Bob’s name \crlf Company \crlf Bob’s street \crlf Bob’s town \crlf Bob’s country \Par My street \crlf My town \crlf My country \blank My phone number \blank Today's date \stopPar Dear Bob, Blah blah blah \stoptext
