Hi all,<br>
I just thought this talk might be interesting to the Swift and Falkon
community, feel free to come by today at 4:30PM in RI405 at UChicago
for the talk. Also, sorry for the short notice, especially if you
aren't on the UChicago campus.<br>

<pre>Hi all,
This is just a friendly reminder for today's seminar, that will take
place at 4:30PM in RI405.
See you at the seminar,
Ioan
PS: We'll be having some pizza today, instead of the usual chips and
cookies :)
