Events invitation via email?

Looking for some news, about inviting friends to events, especially via emails. Do you know how many you can invite at once? And what about the constant changes on FB, it worked two days, ago tested a while ago and it apperas not to work. Also looking for any scripts, that could upload emails from a txt to the event invite. Help and comments greatly appreciated

I would wait untill FB makes their mind up lol.My bot can do this but like you said it changes almost day to day.

yesterday I was trying to make it manually and not working. seems that FB bug.

In fan pages you can read "*Maximum of 5,000 contacts supported.".

In events i don't know..
