How do you make a link?

  1. I don't know if this is the right place to ask, but I can't figure out how to make a link! I've been keeping a blog for almost two months now but haven't put in any links...I think it would be a pretty good thing to know. Thanks in advance!
  2. What exactly do you mean? You have links in your signature... but do you mean link a specific part of text so when you scroll over it you can click on the link?
