Platinum Membership Upgrade

I just ordered mine. But didn't get approved as of yet. Is there a waiting period?
Platinum Memberships are now available for purchase, and include the features below. Registered members do not have the below functions.

1. Search function enabled
2. Delete own posts and own threads
3. Edit own posts and thread titles
4. Edit signature
5. Delete other users ratings and likes.
6. Edit profile
7. Removes 90% of ads
I just signed up and upgraded to Platinum but can't seem to find the search function or edit signature.
Any help would be appreciated.
