Subject Re: [PROPOSAL] Incubate Wicket
Date Wed, 26 Jul 2006 16:04:52 GMT
This has my hearty +1!  This is great news as I've always admired the
framework and the community behind it, and this will further
facilitate the inter-framework discussions we (Struts) has been
periodically having with Wicket.

Let me know of any way I can help,
