To use SourceForge for development, you need to register as a site user.
Head on over to http://www.sourceforge.net/ and follow the link, `New User Via SSL'. There, you will be presented with the SourceForge New Account Registration page. You will need to fill in the following details:
Login Name -- Set it to anything you like. This will also be your SourceForge email address.
Password (min. 6 chars) -- Your SourceForge password is used for nearly everything you might want to do at the site. Choose it carefully.
Full/Real Name--This one is required.
Language Choice -- If your preferred language is anything but English, change it here. If needed, this can be changed later.
Timezone -- By default, this is set to GMT (Greenwich Mean Time). While you are not required to set this correctly, it is helpful as it can tell people when they might expect a response to their email.
Email Address -- Your email address must be correct or you will never be able to use your account at SourceForge. This address will not be shown on SourceForge's web site, but you will receive a mail forwarding account at <login@users.sourceforge.net> that will forward to this address.
To join the newbieDoc developers list you must contact one of the project administrators. To find out who these are, have a look at http://sourceforge.net/projects/newbiedoc/. Follow one or more of the links in the developer info box to find contact details. Send an e-mail to any or all of the admins explaining that you wish to become a developer, and be sure to tell them your SourceForge user name.
