How long do I have to wait before I can post any links?

I received the following note when I tried to post a link:

The following errors occurred with your submission:

1. You are NOT allowed to post URLs, email addresses and images, until after you have been a member of BHW for a little longer. We did this is to cut down on spam. Thank you for understanding! If you would like to remove this limit faster please consider donating HERE

So, how long do I have to wait before I can start posting links??
