Welcome to Ragnarok. Here are three LSs to consider. (And there are still more in the stickied thread in this server forum.)
- my own LS, Axiom, with about 25-30 members of all levels (axiom-online.org)
- Triumvirate, a larger shell heavier on the medium and lower-level jobs but with several higher-level folks too
- Musketeers, a larger shell perhaps weighted to the veteran side, but welcoming to newer players too
Triumvirate was, I believe, experimenting with Ventrilo recently. AFAKI, though, neither Axiom nor Musketeers routinely use Ventrilo (or TeamSpeak etc.).
If you need any help in-game, try to find me online (Grommet).
