You need to have 25points and 15 posts before you can become a full member and can then have an Avi picture, post pictures, have a signature, start new threads, edit posts , post links that show up correctly and have quotes appear in grey boxes . This thread explains about it.
You receive a point each time another simmer presses like or awesome or insightful on a post that you have posted in a thread created by another simmer.
Because you aren't a member yet, you can't post pictures that appear , but you can upload your pictures to a photo sharing site such as imgur , then right click the picture on the photo sharing site and copy/paste the image address link in a post on the challenge thread. I can then post the pictures for you :)
You will need though to replace the http in the address of the images with h.t.t.p as you are a new member and can’t post links.
