Pligg Support

I want to know what does it mean? and how can i unblock my ip. Please help! And Which words are counted as anti spam?
the title says it all i need to import just the emails of all users into mailchimp to run a real email campaign that isnt just plain text to all of my users. i can "send announcement" but im not sending people a text only page that seems not right.

if there is no option for this can the current "make announcement" form use HTML?
