This must be one of the longest time period to see Mixtum service and website are not available.
It doesnt look good to continue advertising in forum and signatures if you cant use this service.
Does anyone know they are coming back online and finishing this maintanence?
I fundamentally disagree with you.
Promotion through a signature campaign is a long-term strategy that requires a lot of effort and time for the brand to take its rightful place in the niche. And neither I nor MixTum believe that a maintenance break should in any way affect the campaign.
The core of our community (in particular MixTum supporters) should feel confident regardless of the circumstances.
p.s. Those works are related to the fact that Jumbler is updating its security system, so this affected MixTum.
