Make sure you don't pick a good password for ekiga.net -- they mail it back to you IN THE CLEAR in an e-mail message.
I'm so furious, I can't even begin to describe it. Did I miss fine-print on their page saying they'd do something this stupid?
UPDATE: They also store your password in the clear on-disk. Check out ~/.gconf/apps/ekiga/protocols/%gconf.xml if you wanna see it in all of its cleartext glory!
