I got a letter today saying that Comptia was changing their certification expiration for A+, Network+, and Security+ from lifetime to 3 years as of Jan. 1, 2011. That means if you take the test now, it won't expire but if you take it after that date, you have to recert every 3 years.

Just thought I'd pass it along for those considering any of these certifications in the relative near future.
