Here at ABC Articles we post rather random articles on a range of subjects so that you can get backlinks from relevant pages. The system is not finalized yet, but in the future you will be able to get free in-text backlinks from all of our posts. The only thing required in return is to link back to us from your own site or blog. (offcourse these will also be relevant links as we cover a lot of subjects.)
Trackbacks are also always accepted!
