People don't understand certificates. At all. Which is why they were
perfectly willing to download certificates for the omega server from any
blog/host that happened to have them up. That page is hosted on the server, the pem files come from the pidgin source, those exact
files will be in the next release of pidgin which people will implicitly
trust when they upgrade, etc.

Any text talking about verifying things is going to complicate and confuse
the situation more than I think it could possibly help though I do
appreciate the thinking that goes into requesting it.

I'm open to adding a note to the bottom explaining the potential dangers
with doing this sort of thing but anything more than that I think would be
too much.
