The first is an extensive database almost of recipes that are submitted and put up for comment and alterations. They have recipes for every single situation you can imagine and also provide feedback in the form of comments, etc.
The second is a blog posted by a vegan activist, whose other blogs and sites are also listed... and she shares daily menus which she's prepared for her son ("The Shmoo") who she is raising vegan.
Hope that helps.
Also, I'm a returning vegan myself, and I've noticed the same thing about online veg*n communities. I've even found threads on some of the MySpace groups where people have talked about needing to "gain weight"... hard to relate on that issue (although I've been at that end of the spectrum only a few years ago... )
It's an untrue myth that people expect veg*ns to be skinny as rails. It's just not true. My mother has been vegan for as long as I've known her (all my life, that is!) and she has always had weight issues... only recently lost substantial weight, and still is what most would consider "overweight"...
