Oh right... I completely forgot about this (my colleagues will kill me when

Yes, in that case, a general "call to arms" on mailing lists is maybe not
the best approach. Maybe building a list of people who are interested
participating in such studies in the future could help lower the
frustration of not being able to participate (but I wonder if it would not
introduce a bias in the studies).

To provide such "free" feedback, did the UX team have some entry points we
could spread about? (Mailing list, blog, twitter account, dedicated web
sites, etc.)

Yeah \o/ (again)

Definitely, thank you very much :)
