Everyone on that
list has volunteered to help train people new to the mod like yourself, so don't worry about PMing any of them.
In fact if they are anything like me they enjoy training, it's a nice change to competitive play, is our way of helping being involved in expanding the playerbase, and often helps us analyse our own tactics/gameplay style.
Also, get yourself on the MWLL Outreach
TS3 server, chances are someone on that list will be on there (ts9.gameservers.com:9144)
