I've been stuck at level 32 for months

I think this is the second post of someone saying (albeit indirectly this time) that they can't find a Castle Entrance group in MM.

Sounds like there's no active group recruiters anymore... people just turn up, see that there's no action and move on. Stick around, grab a healer.

/who all cleric 27 35
/who all druid 29 35
/who all shaman 27 35

...get something started. If you do well, people will not only come back, but they'll look to group with you again, put you on their friends list and say "hi" when you're on.

The more social you are during the levelling process the easier it is (except for necros, who aren't required and can do better on their own).
