You do not need to register with this site to view or download the latest version of the spiders list.
If you want to submit new spider(s), you can submit to the official thread on vBulletin.com.
NOTE: I realised that there are no hacks out there that make any use of the info or email fields that I have been including in the spiders_vbulletin.xml file (it also seems that vBulletin does not use the fields either), so I have stopped including the fields in the xml file, hence the smaller file size from now on.
