Late filing (2007 tax year)

I have still not filed my 2007 tax return and am working on it right now.

I will not owe any tax and will be filing 1040 and 2555 forms.

My question to anyone is...do I need to do anything else to ensure I can still still take advantage of the foreigned earned income exclusion?

I am planning on mailing my tax return tomorrow, if that helps.

Thanks!
