How popular/active is red server? Thinkin of trying it out. Couple questions?

[VincentVolaju]

So I am considering making a char on Red, but my biggest concern is there just wont be enough people playing it. That most zones will be empty, there will be hardly any trading, and just in general not very populated and will be forced to solo 90% of the time.

Was also wondering which classes are the least played here / groups usually short of?

Lastly, how is the leveling experience 1-40/50 ish? Are there many pub groups looking for more, or is it pretty much just a set group of 3-4 friends leveling together at specific times?
