Being a new member, having some sort of document emailed to me would have been amazing! I’m the sort of person who will go searching for information I need but I know not everyone else is. Something as simple as links to the wiki, talk, calendar, etc. would probably be helpful for some (I know it’s on the web page but some folks may not always check there). Contacts for each area would also be helpful in getting into some of the training we need for the tools. People who don’t use forums often probably do not know to tag a group or person to get their attention. I use forums regularly and still forget to do that sometimes. All that to say, the simpler it is for a new member to get started the more likely they are to be actively involved.
Just my 2 cents.
