Here's the existing front page blurb:
The True Role-playing Game!
Cantr II is a 100% free persistent browser-based role-playing game (PBBRPG), in which players can play roles of self-developed characters who all together form different societies of many languages all over one great Cantr World.

For the love of God, get rid of the "true role-playing game" blurb at the top. It sounds elitist... and wrong. Cantr is ten years old according to its front page. Fifteen years ago, I was roleplaying online. Twelve years ago, I was roleplaying on MUDs online. Until Cantr has a wikipedia page stating it is historically the truest roleplaying game around... Yeah, just remove that blurb.
For the rest, something like...
Cantr II is a 100% free, persistent browser-based role-playing game (PBBRPG) where the world, its cultures, societies, history, religions, and objects are all created by players, playing as the characters that inhabit that world. Considered by many to be a slow-paced game, Cantr offers the possibility for enjoyment even with limited playing time. However, if slow isn't your style, you can play up to 15 unique characters, and it's up to you how far they are involved in each of their communities. With a rich, living history and support for sixteen languages, the possibilities in Cantr are almost endless. Play as a politician, a pirate, a poet, a feared conqueror, a trader, an artisan, a courtesan, or as an explorer in an ever-changing world that is affected by the choices you make in game. Don't believe us? Check out the testimonials below.
[Testimonial video here. Get players to post about (bonus points for narration in a video) their experiences on Cantr. If players are unwilling to narrate themselves, find a handful of people who aren't afraid of narration and get them to read a few short posts about Cantr experiences. Character experiences, preferrably. Interesting ones. Additionally - no music. Get other players to sketch a few short scenes from each experience, and slideshow those to the testimonials. No cheese. Just simple cuts. No Engrish.]
Also, remove the CLICK HERE TO JOIN and instead add a "Create a New Account" or "Register" option on the sidebar. CLICK HERE TO JOIN sounds desperate and pleading. You never want to look desperate.
Stop bolding the wrong things, too. Don't bold the bits that talk about how you HAVE TO play. Bold the bits that talk about HOW you can play and WHAT you can do.
