So the 64 dollar question is,is Bitmixer open or not to sigs

It is closed for new participants. Only people that are already or was in the past in their campaign can still join.

If I try with your uid, I get this, so you can't join anymore.

Too bad for newer folks but I'm glad that older folks can still rejoin, I plan on advertising for bitmixer again in about a month once I get my silver wallet campaign payout.

cloudminr.io don't have free spots..
There is mistake in OP:

PD appears to be reopening soon. This should increase overall advertising rates for everyone

Does anybody know if the first 777 signature campaign is still running?
Last payment received was about 2 weeks ago but i cant get an answer to this from Lightlord or anyone else i have tried, any help would be much appreciated.

If you check current list of enrolled members, your name is not there

Ooh, this is the news everyone has been waiting for and the "bigger & better than ever" has me intrigued. My deal runs out this month and I'll be a Senior too soon so the timing is perfect. Can hilariousanco gives us any details on what the new campaign will be like? Fixed campaign or per post etc?

Do you have any details as to the time frames when the campaign may start?

Ah geez H@C the way you worded that I'm thinking of PD3 all over again  
Well at least it will come it beats a BFL 2 Weeks ^TM anyday haha
Otherwise pretty quiet on the sig campaign front atm
