Main Question or Discussion Point
Are there any good online introductions to topology?
I did Topology before Analysis and I found it to be fine, in fact probably better. Of course, Metric Spaces is easier after Analysis and so on.It would be a little rough doing topology without first doing some proof based calculus.
Even for Munkres I doubt you need any pre-requisites.there is a high school level intro to topology by chinn and steenrod, with almost "no" prerequisites. it is excellent, chinn is a decorated high school teacher and steenrod is one of the most outstanding topologists of the 20th century, from princeton.
