Since I am not a module author, I am not sure how valuable my opinion would be, but with what I saw of the site you already have going, I was pleased with the organization and layout. I think it is great that you are trying to mobilize all perl user towards a common goal fo making the language easier for not only the module writer, but the newcomers.

I honestly like the forum approach. With a mailing list you might have some of you followers who are on the inside of the inner workings of the modules, but with a forum I see a way for someone to come in and either ask for help making something work, or someone to write a suggestion, everyone takes it and tweaks until they can make it work, submit it to the author, and everyone is happy with a final working product that was built by an entire Perl community. In my opinion, I think that is what makes the monastery great, and what makes it so successful.

Whichever you choose, I think you are doing something very great to bring us all together, and I offer any help I could possibly contribute.
