Trying to use Django, do I need to install Apache manually if Wamp already did
You don't need Apache at all at this point. For development, things work much better if you use the built in development server, as described in the tutorial.
To make my question clear:

I have had wamp installed, and it brought Apache. Will this Apache be used by others like Django?
If the wamp Apache is enough for others, its Apache is in wamp directory C:\wamp\bin\apache, not sth like C:\programs file...It is ok for django
If I have to install Apache manually for django, will the step be install Apache, install mod_wsgi?

Any help would be greatly appreciated
