The last F&F beta event starts Friday. So the next phase will be the main testing. Invites could be seen as early as 3 weeks before the first wave of testing.

First wave testing is on March 30th and 31st confirmed via twitter.
First wave of invites went out today.

this.

I was very lucky to put my hands on the closed beta for few hours and I can say the game won't be anything like WOW

the mechanics are completely different from wow

Anyway it looks rly rly great combat, skills everything I could test was great.

The only thing I didn't like was that sneaking around drains stamina, at least in the low levels.

I rly like stealthy role and I know this will be bad

it would be o/p as hell if it didn't though :/

So far there hasn't been another beta event since the one on March 28th. However expect a new round of invites soon. From how all of them have been going, they are doing a beta event 1-2 times a month.

Whack.
I hope I get an invite.

I don't understand why I didn't -.-
I submitted like the day it opened.

As of right now there has only been F&F events. However the next test should begin the official closed beta. May have sent out some preemptive invites to it, however I think the only invites that have gone out are for F&F which are invited to all the beta events. So don't fret, you may still have a chance, from what I have seen on the major fansites, myself and 1 other are the only two to have participated and or gotten invites. Which is a pretty good indication that they have only sent out an EXTREAMLY small number of invites.

I hope to get an invite for myself so I can play it a little longer

Was crafting open in the first beta wave?
