&lt;br /&gt;
Dear Knot at Lunch People,&lt;br /&gt;
&lt;br /&gt;
We will have our next summer lunch on Thursday August 16, 2007, at the usual place, Bahen 6180, at 12 noon.&lt;br /&gt;
&lt;br /&gt;
As always, please bring brown-bag lunch and fresh ideas. I&amp;#039;m not yet sure what the agenda will be - perhaps we will continue with the topic from our [[Knot at Lunch, July 19, 2007|last meeting]], or perhaps it will be something else.&lt;br /&gt;
&lt;br /&gt;
As always, if you know anyone I should add to this mailing list or if you wish to be removed from this mailing list please let me know. To prevent junk accumulation in mailboxes, I will actively remove inactive people unless they request otherwise.&lt;br /&gt;
&lt;br /&gt;
Best,&lt;br /&gt;
&lt;br /&gt;
Dror.&lt;/div&gt;</summary>
