Getting a high page rank backlink from a reputable site

Getting a high page rank backlink from a reputable site

Here's an idea that might work for you to get a very high page rank back link from a reputable site.

Create an account and post actively on the official forum for your forum software. So for instance, if you have SMF, then you would register and post on the SMF forum site.

The same goes for MyBB and Xenforo. There is usually an official support forum for every forum software. Most will allow you to create a signature line, linking to your forum assuming it uses the same forum software.

Most of these forums will not allow you to talk about or advertise (signatures, exchange requests, etc), if you don't use the forum software they are supporting. So if you have a Xenforo forum, don't post on the MyBB forum.

Here are some official links:

http://www.simplemachines.org/community/
http://community.mybb.com/
http://xenforo.com/community/

Please suggest other specific forums that allow a backlink (only high page rank), either by advertising or signature line. Or, suggest a unique way to get a backlink.
