title: How do I delete a wrongly tagged directory in SVN?
body: <p>I have a project Foo which I errantly created the wrong tag for. It should've read 'rMMDDYYYY' but I tagged it 'YYYYMMDD' instead. I realized my mistake after having commited my change. I now want to remove the YYYYMMDD folder under the tags directory and leave the rMMDDYYYY folder instead. i.e.</p>
  
  <p>before:
   foo/    foo/trunk/   foo/branches/    foo/tags/    foo/tags/YYYYMMDD/   foo/tags/rMMDDYYYY</p>
  
  <p>after:
   foo/    foo/trunk/   foo/branches/    foo/tags/    foo/tags/rMMDDYYYY</p>
  
  <p>Any idea how I can do this please? Thanks in advance!</p>
