<p>To create a wallet, if you have only a survex file and nothing to upload into the wallet,
you currently need to got to <a href="/scanupload/">Upload Scans</a>, navigate to the new wallet number 
and then upload a dummy file, e.g. 'nothingyet.txt'. You can then edit the wallet details: the date,
the people involved, and the url of the survexfile which you will already have uploaded using e.g.  
<a href="/survexfile/caves-1623/290/mynewsurvex.svx">/survexfile/caves-1623/290/mynewsurvex.svx</a> 
(for a survex file for cave 1623-290).
