You should preferably start a new thread under "Aquascaping and Member's Setups" and upload your pics via the "Upload a File" tab . Alternatively, you can use an image hosting site such as Flickr or Photobucket and add a link to your shared pics in (for example) your signature on forum.
Click or tap the "Members" tab up top. On your right (under progress bar) you'll see "Find member". Type in the members nick or part thereof and it'll show you a list of member names that start with what you typed.
