First get yourself to a respectable rank, then get a good post quality. After that learn how to read and you'll find it very very easy to get into a campaign.
OP is a Jr. Member and I don't think that it ain't a "respectable" rank here??? Even few campaigns accept newbies, and many came just for Jr. Members, then why he can't get into a campaign being a Jr. Member and why should he wait till he reaches a respectable rank???
He would still make something till he becomes a Full or Sr. Member...
