how to upload web changes

As a learning experience I am hosting 2 web sites on a windows computer with apache for some friends. Using the default setup and htdocs we have two folders in there one for each site .We just copied all the files needed into each one.
Everything works fine and it is listening to port 80 and runs off of a dsl modem.
The question is?
Can someone point us to a tutorial on what to do next so they can use Ws-ftp from there home computers to log in secure and
upload web changes to there folder on the server.

example
http://mydomain.com/bob - his web folder
using Ws-ftp at home looking for port 80 - ??settings
ftp.mydomain.com/bob

anyone have some example configs or something to get us started in the right direction. Thanks!

>> they can use Ws-ftp from there home computers to log in secure

If you want security, don't run servers on win32. FTP is not a secure protocol by design, therefore, to compensate this some FTP servers on win32 is SSL/TLS-aware. Just to name a few: CuteFTP Pro server, WS_FTP server and FTP Serv-U Pro.

>> Can someone point us to a tutorial

Go to the appropriate site and read their docs.

>> his web folder using Ws-ftp at home looking for port 80 - ??settings

FTP uses port 21, not port 80. Web server has nothing to do with FTP server at all. What you really need to do is to setup a FTP server so your friends can login to the appropriate folder (the exact one for their web root).

>> anyone have some example configs

I thought you use Frontpage. So why don't you just set up FP extension so your friends can publish their web contents right from FP explorer? On the other hand, if you are interested in setting up a FTP server, just do a search for the name of the FTP servers I mentioned above.

Thanks that will get us started.
ftp port 21 question.
I'm using a cisco 675 dsl device and we had to program it- I think it was something like set nat entry to make the dsl ip forward to our server ip on port 80.
So I guess we do the same thing for port 21 ?? and it listens to two ports?
Thanks for the help - will read the ftp server docs.

>> and it listens to two ports?

Yes, two type of different daemons, thus two different ports.

thanks for the tips- tried Serv-U pro and it was easy to setup and use. Worked great ! thanks again
We also used the Snitz forum package before on one of our sites,but it uses asp to run it, and from reading the apache docs it won't support it. Anyone have recommendations of a free forum package we could use on a site using the apache server.
This one vbulletin isn't free to use?

A good free forum that you may want to check out is phpBB - http://www.phpbb.com.
