<h3>Expenses and money owed</h3>
<p>As well as writing the amounts of money in the books, printed receipts for expo expenses need to be put in the envelope in the potato hut.
<p>Each receipt needs the name of the person paying and a sequence number if you have more than one receipt.
<p>Each receipt needs
<ul>
<li>the <b>name</b> of the person paying written on it in biro
<li>a sequence <b>number</b> ("1" if you only have one receipt to claim)
<li>the amount claimed <b>ringed</b> in biro - hand written if it is not thesame as the total printed
<li>the date on the receipt <b>ringed</b> in biro
</ul>
because matching up receipts with scribbles in the bier book is very time-consuming / impossible
otherwise and you may not get paid back.
<p>Both expo communal expenses and shared group expenses should be entered into your <a href="bankofexpo.html">Bank of Expo</a> online account. When you have typed it in, make a written note "BoE done" against that line in the book. (If you don't do this the expo treasurer will
have to do it. And you want to keep the expo treasurer happy don't you?)

Configuring these to be used via WiFi is yet to be done. Meanwhile, use a usb stick to transfer files for printing.
We have A4 printer and scanner attached via usb cables and a usb hub (and coffee warmer) to the <em>Expo laptop</em>.
In 2018 we also connected the printer to the router with an ethernet cable and this made things more reliable.
Configuring the scanner to be used via WiFi is yet to be done, but the printer is "shared" by the
<em>Expo laptop</em> and so canbe usedby any laptop. (The printer has WiFi itself and so should be useable
directly but we haven't got this configured properly yet.) Use a usb stick to transfer files for printing
if you can't get your own laptop or phone to work with the printer.
<h3>Networking Hardware - experts only</h3>
<p>The networking hardware is an Acer Aspire netbook which keeps us logged in to the Gasthof and does firewalling, plus a WNDR4000 router/AP
to provide local connectivity and local WiFi. The antenna which we use to connect to the Staudnwirt WiFi
is a ~32cm long black stick mounted on a small shelf high above the sink/stove area and connected via a usb cable to the Acer netbook.</p>

<p>Prior to 2018 we used to run an unconnected local network with our own DNS domain
name "potato.hut", our own server holding all the website and survey data, and published WiFi as SSID "tattyhut".

the tatty hut to a real internet connection and
