==Invitation==&lt;br /&gt;
&lt;br /&gt;
Dear Knot at Lunch People,&lt;br /&gt;
&lt;br /&gt;
We will have our next not lunch on Wednesday February 11, in my office (Bahen 6178) at 2PM.&lt;br /&gt;
&lt;br /&gt;
Peter Lee will bring goodies, and I beg him to keep it modest - we don&amp;#039;t want to get into an escalating goodies-quality-war! After goodies, Jana will tell us more about the Alexander polynomial for tangles, or, as always, we may talk about something else.&lt;br /&gt;
&lt;br /&gt;
Further information about this Knot at Lunch meeting may be posted later at &amp;lt;span class=&amp;quot;plainlinks&amp;quot;&amp;gt;{{SERVER}}/drorbn?title={{PAGENAMEE}}&amp;lt;/span&amp;gt;.&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>
