If it's the kind of information that you want to be anonymous when you post perhaps you should think twice before posting it publicly. We have had more than one member loose his job over postings on this site, and probably a few more before I got involved here in 2006 and actively as a mod in 2008...
If you'd like, you can email one of the Wiki admins (me or W9RXR) or Lindsay with the info and we can put it up for you...
That said, if someone with a badge comes a'knocking asking who posted it, you better believe I'm gonna sing like a bird (or defer to Lindsay) :lol:
Like Lindsay said, the problem with anonymous editing is the spammers would go nuts - at Wikipedia they literally have thousands of people and automated tools to check edits for spammers - and we don't :wink:...
