Mi spiace ma non puoi linkare quel tipo di sito.

How to make anchors and link inside posts
This board has anchoring and linking within posts enabled.

• To make anchors within your posts, just specify [anchor]anchorname[/anchor].
• To link to that anchor:
  1. From within that post, use [goto=anchorname]text[/goto].
  2. From another post on the same page, use [goto=postnum,anchorname]text[/goto].
  3. From another post on a different page, use [gotopost=postnum,anchorname]text[/gotopost].
• You can also use goto and gotopost to link to the top of any post:
  1. [goto=postnum]text[/goto] if the other post is on the same page,
  2. Otherwise use [gotopost=postnum]text[/gotopost]
