Which means:

HOW THE EUROPEAN UNION WORKS

C.  Entitlement to vote

1.  Vote of non-nationals in the host country

Voting age is 18 in all the Member States.

I take it the age is set on EU level? Then I think it is appropriate to tie these two together. Unless one wants to use this as an opportunity to push it downwards, then 16 is probably a good suggestion.

A vote for PES is a vote for EPP! A vote for EPP is a vote for PES! Support the coalition, vote EPP-PES in 2009!

I agree that age eligibility should be linked to EP elections criteria.  However, reflecting the more informal and less binding nature of an ECI, the method of voting/ or collection of sigs should be made much easier/less inconvenient that physically going to a sig collection location and more encouraging and participative and thus some form of online collection is imperative - otherwise the barriers to raising any ECI are prohibitive for all but the largest and best funded organisations.
