I just switched my own Twitter account from Twimailer to Topify. It was very simple (and I'm much less worried about security) because I never actually changed my email address in my settings on Twitter.com. All routing of messages to Twimailer (and now to Topify) was (and is) handled by a filter in Gmail. I know Chris Messina wrote about using Twimailer safely using a very similar filter, but I just published a post that applies to Topify as well: http://voyagerfan5761.blogspot.com/2009... - Voyagerfan5761 from FriendFeed MT Plugin
