What are Wiki links/ contextual... ? In Ultimate Demon, GSA, etc..

ok. im going to start a link building campaign tomorrow. I plan on only using contextual links. So i will focus on Web 2.0s, Press Releases and Article directories(in Ultimate Demon and GSA)...

I wanted to know- what are Wiki links? are those links that go at the end of related dictionary pages of sorts? or do they take the article you submit as well and the link can be embedded?

Also, of the 3 types of links i mentioned in the first paragraph- are those ALL of the types of contextual links to be built(in UD and GSA)?

Thanx in advance

Help Help Help. I have checked this, but cant find good info.

Did you ever find this out? I also have the "what are contextual/wiki links" question
