A question about web hosting

[violenttom]

Hi there,

 

 

I'd really appreciate it if people can help me with this problem:

 

I'm running Apache on a Linux server. I would like to grant some other people access to a specific directory in the server, so that they can build their website there. I'll host their website with my machine. I'm wondering how I shall do that, and what problems (i.e. security issue) I shall pay close attention to when I do that.

 

Any advice would be great. Thanks a lot in advance.
