Our team of moderators is also in charge of moderating and validating the accounts. It is thus normal that your account appears under the status "pending for approval" at the beginning until it is moderated and validated by our team.
The accounts that are usually pending for approval are those where the contractor chose "other" for the professional group when registering on our site.
In fact, the moderator needs to verify that the professional group corresponds really to "other" or if it can be attached to another categorie close to it (communication/marketing, consulting, journalism, etc). I none of these categories correspond, the professional group will stay under "other".
