After reading several dozens of topics I see there are users that drop irrelevant links in their posts in order to gain backlinks. I've edited those posts and removed the links.
If you want to get a backlink from us there are several options:
1) Set a signature for your account here.You can do it by following this link.
2) Write a guest post for us that will be published in our articles section. More details about guest posting here.
3) Purchase advertising from our store. Check the TGF Advertising Kit.
I have to remind you that in your posts you should add only relevant, high quality links. If I'll find more irrelevant links I will warn/suspend your account or posting rights.
