how many instances of "y" are there in:
q: which continuous integration for selenium 2 with testng so i have a selenium automation project (using maven).
i'd like to be able to set my tests to run overnight and possibly email a report daily to the team.
which ci would be most suitable for testng.xml suites?
i tried hudson but i couldn't figure out a way to execute testng files from the build?
thanks in advance.

a: you should be able to use hudson to kick off a maven job (hudson has a maven plugin http://wiki.hudson-ci.org/display/hudson/maven+2+project+plugin works with maven 3) that runs your test, see http://testng.org/doc/maven.html

a: there are different ways that you may try and hudson is one of them. however, you might not find a good resource or article to follow.
here is a nice walk-through how to succeed - continuous integration with selenium 
i would also recommend to look at testng and advanced concepts book for a complete reference.
