Welcome to Diapered Anime, YkIh. All communiations (New threads, posts, VMs and PMs) created by members who have not yet reached the "Junior Member" (Ten to thirty-one posts in the forum sections or the gallery) level of membership are flagged by the system and moderated by the staff. The system only allows you to create three PMs per 24 hours [1440 minutes] so as to allow time for the available staff to moderate your PMs. It may take less than that amount of time for a staff member to approve your PM, so just be patient. After you have attained Junior level membership, your communications will no longer be moderated as long as your continued communications and behavior towards other members do not violate the Forum rules (See ->
here). Your communications may still be monitored immediately after ten posts (It's up to the staff's discretion). Also, when you create a new RP thread, it needs to be approved regardless of your level of membership. I hope that this helps.
