I don't want to rub the forum the wrong way, but isn't the purpose of a forum to get and share help ?
Being new here as I look arround I am shocked at all the never answered posts, far to many IMHO.
Does the creators even check out the Yate Client Linux section ? there are allot of unanswered posts there.
Oh, and by the way, when you login, it asks for your username. It's really not wanting your username. It's wanting your e-mail address. For the love of common sense, change it to something else like e-mail. Or leave it an actually accept the username.
