Jenova is a nice server. We're about average in population from what I remember of the last unofficial census. There's also fair sized communities for raiding, RP, hunting and crafting so there's kind of something for everyone here. Its big enough that you can generally find people to do things with through /shout or PF and I generally see lots of PF groups at any time of day except early morning (early as in 5am est time)...you know when most sane people are sleeping.

Its not a perfect server, but I couldn't imagine leaving it.
