I'm not sure if this is a twitter module issue, a views issue, or some drupal settings issue and google searches are proving useless.
I'm using the twitter module and views to create a block of recent tweets. It's fine, except that tweets that start with a period/at, like .@twittername, become mailto:.@twittername links, as opposed to the normal href=twitter.com/twittername.
In the twitter database table, there is no mailto. This is inserted when using the view and I've found no option in views to resolve this.
