Bug reports and feature requests should be submitted using the trackers only. Before posting a new request, please make sure noone else has reported it yet.
You are also invited to join the official FileZilla IRC channel: #filezilla on chat.freenode.net
You can also mail me directly, but please refrain from mailing me support requests, feature requests or sending bug reports, for those the forums and trackers should be used. My mail address is firstname.lastname@example.org. Don't expect a reply for questions about how to use FileZilla, I get so many, I simply can't answer them all. Please use forums instead. Don't send me attachments in proprietary formats (.doc, .rar and the likes), I just can't open them.
