This problem should only be affecting posters with less than a certain number of posts. Because we are a pretty high-traffic site, high ranking we have a large number of spammers that attempt to post here, either selling their worthless crap, or trying to promote their website. We use a whole bunch of automated tools that filter and detect posts that are likely to be spam, and those posts, particularly from new members, get thrown into the moderation queue. Usually, the automated tools are extremely accurate, but recently they have been flagging posts that don't seem to have any obvious reason for flagging. We're trying to be more diligent about checking the moderation queue more frequently, but right now, it may take up to a few hours to have it reviewed and released if your post gets flagged. (Once you've made a bunch of posts, your messages will no longer be subject to the automated filter.) I apologize for the problem. We're working on it as we speak, but it's a tough balance; I would rather temporarily delay a handful of posts and catch the spam posts, than set the filters too low and let the spam through, because that almost immediately increases the amount of spam, as soon as spammers figure out ways they can (temporarily) evade our moderation. New members and new contributions to degreeinfo help keep the board lively, as well as contributing to the combined knowledge and conversation, so it is important to us that new members not be "put off" by the moderation. We really appreciate your understanding.
