This is the weekend and many of the Moderators are busy and not here.
Besides checking that your minimum of 3 review posts within the past month are "quality", your site needs to meet certain criteria eg. nothing illegal.
If everything is OK, your request for a review should be approved as soon as a Moderator checks everything. If not, you should receive a Private Message explaining what the problem is.
Try to be patient as the process is not automated and requires a volunteer Staff member to spend some time to do everything.
