As we approach the mid review of Ion Gaztañaga's Intrusive library, I would like to encourage you to consider submitting your review reports. So far we've received three reviews only, I hope more Boost members step in and contribute to this global effort which constitutes the cornerstone of Boost renowned quality standards. If you love and use Boost, remember that active involvement is a nice way of repaying the benefit you have obtained from this community.
