1) Use only Internet Explorer with the site to actually see something in the posts.
2) Once you join don't hurry to download & run. Just take your time (when you got some to spare

) and read the guide, then read the sticky posts, even maby some quick guides there.
3) Then if you play on L2J (not other weirdo servers who modify the client) just use one of the following:
v6x - Interlude
v7.0 - v7.1.5 for Kamael CT1
v7.2.1 for Kamael Hellbound (official and L2J)
You may be initially confused for a few days because of the complexity, you will probably be annoyed by some bugs (check the Bugs section) and you might have some questions (possibly that someone will help you there).
All in all, 5 stars for a FREE bot. Maby L2Walker and Superman outperform this one sometimes but ... no more cracked .dll's, workarounds, $$$, etc. - thank *** !
Even GG runs along untouched with the IG mod.
Wrote this because I laughed @ ppl's paranoia. Sometimes caution must be used, but with moderation.

P.S.: Have been using it for 5 and 1/2 months now on official NA

P.S.2: For the guy stating that nobody uses it

- my server was light until Hellbound version was ready - now it got back to normal and high ^^
