Since you can now invite colleagues to join you in a site's private beta (which I think is great), I wanted to make a request to make this feature a little better. I just used it to invite someone to the Movies Stack Exchange private beta, but I was really surprised that there was no option to customize - or even view - the invite message before it was sent.
I think it would be useful to have the ability to customize or add on a personal message to the invitation. For example, the person I was sending the invite to is
obsessed with knowledgeable about James Bond movies, so I specifically wanted to tell her that this would be a great place to share that expertise.
Since the reason behind that feature is to invite people you know are experts (and probably have some sort of relationship with), it makes sense to me to allow a personal message that might be more convincing than a form letter.
Is customizing the invite message a possibility? Even if if was just a pop-up box that adds on a personal message to the form letter part of the invite (i.e., I don't necessarily need to be able to change Stack Exchange's pre-written part), it would be useful.
