I've two questions,
1. I've joined the campaign when I was full member, which is today and now I'm Sr. member which is also today, I will be paid as Sr. member, right ?
2. I'm enjoying posting at the off-topic section, will these posts count ?
Of course OT posts count if they are constructive (not trolling nor i agree with...)
Past cases like your was paid based on the last member status (So you should expect to be paid as a senior member)
Many keep saying "don't post so much in off-topic" for the PD campaign. This is weird they think that those posts shouldn't count. I mean, as long as they are related to the thread and constructive, why not? Many people frequent that part of the forum too and will have a chance to see the banner and get familiar with PrimeDice through your signature that way.
