It'll take a little while due to dirtweek & the fact Okie is relocating (i.e. bad timing).
Once you've got "subscriber" under your name, you'll be able to edit your posts, you'll be able to send PM's (private messages), and whatever else (dunno, never looked into what non-subscribers can't do).
If you haven't heard back in about a week, yell out then - it may be longer, not sure.
Oh, you'll be able to access the subscriber's forum, post new threads in the for sale/wanted forum too.
Welcome to the club & be patient grasshopper, it'll happen soon :)
