Some sites say something like  "If you have some information you would like to contribute to this website, please email: webmaster@wewillgetbacktoyou.com"

Those days are over!

You should not have to beg for a webmaster's attention to make a change to a community web site -- that is a fundamental reason why so many sites are obsolete and uninteresting.  Every trusted member of the community should be able to edit and should be able to do it from a web browser and without having to learn HTML or any other odd language.

To change this site, first register. You will be able to change much of it, and depending on which groups you join you can change all of it. No software installation or web/HTML knowledge is needed.
