It seems that in the latest issue of PHP Magazine there's a review of the Seagull framework along with a few others - as noted by Demian Turner.

One of the leading PHP publications, International PHP Magazine, has a roundup of PHP frameworks by Elizabeth Naramore in its latest issue. I'm happy to say that Seagull got a glowing review, and out of the 5 projects examined, including PRADO, Cake, Mojavi and php.MVC, Seagull got the highest rating - something like 4 3/4 stars out of 5 - way to go!

Unfortunately it appears PHP Magazine does not provide PDF downloads of individual issues like all the other mags, so you'll have to physically walk over to the newsagent if you want the full story.

Congrats to Demian and the whole Seagull team! Keep up the great work!
