Password protecting from duplicates, etc

[okc]

What's to stop someone from giving out their username & password to a friend if I set up a members only content forum? Couldn't they both login & get the content? Are there any protections for this?

thx

well you can always check the ips to see if this happening, and then you can handle it as you wish.

where are the ips listed, & don't a fair number of people logon with variable/non-static ips?

thx
