ahoy pirates...
wanted to checked if WiHD is open for registration through invite ?

WiHD is always open if you have invite,
Believe me or not, its not that hard to join there if you know anyone who is member there. They credit you with invites for donation you make or for contribution, both are very easy to reach, donation are small 5-10 EUR, few donation like that in few months and you will be credited with invites,
So whenever someone tell that is hard to join, actually it isnt! But, and that is big BUT, French members of WiHD like to make drama of everything, so... I would suggest finding non French members for invite.
Few things:
VPN is big NOPE! You will be banned in a second!
Who ever invite you will have to confirm you or to be more exact... your IP address. So, all have to be in order before they allow you to login after you register.
As for activity, if you dont login for two weeks or even if staff notice that you are not active dow, upl, forum or IRC, they will ban you without a regret and there is no coming back! Well... maybe generous donation will help, if you manage to contact them because there is no way to contact them AT ALL, LOL...
Most important... you must have really biiig seedbox, I mean... alot of space and seed like crazy.
Bottom line... if you are into French staff and if you are willing to make some efforts, WiHD is place for you,
Good luck!
P.S.
They forum, they "Invites" part of forum is very active and they are very generous regarding inviting people to other tracker, but... you will have to work you way up before they take you seriously...

Oh, I forget, I am not members there any more, account is dead for long time now...

Little help, you must have "something good" to offer for WiHD" the fastest way to get WiHD invite is if you have DB9 invite (dont ask me why, I have no idea, but they are crazy for DB9), for start... you are member of very good place to a accomplish that...
