I’ve just found a wordpress plugin for rewarding your commentators. When they comment on your post, they are asked to give their name with specific format. It will give them improved anchor text.
If they enter “Stephen@Custom WordPress Plugins” in the Name field, their comment will have:
Stephen from Custom WordPress Plugins Says:
Stephen@Custom WordPress Plugins Says:
If they don’t enter the @ symbol, the anchor text will simply display as normal.
