Hi,
this is really a great initiative. I immediately thought that you should report the experiences you'll have with this so it can be copied by other EU chapters. Having an "organisation from home" asking for something is often more efficient than receiving a letter from an interntional HQ. Ideally, the two will be complementing each other (like in our case).
As to Mathias' comment on the MEPs: Yes, there will be some considerable turnover, but at the same time politicians are most likely to pay attention to such a thing before election time. Sending it out just to the ones we believe might get reelected would be - diplomatically speaking - bad diplomacy. Can't we just resend it after the elections to just the newly elected MEPs?
As to the length, indeed three pages might be a bit long, but if the opening (i.e. the first page) is informative and interesting enough and the other two pages are additional information, this could just work.
