Hi BlackOrchid,

there is no IP blocker. But you can block users in the chat by clicking on the symbol left of the user name.

In version 5 and 5.2 it works like described here: http://www.flatcast.com/de/FcForum.aspx?forum=49370#49381

For blocking guests you need to enable the guest filter.

For version 5.2, see here: http://www.flatcast.com/de/FcForum.aspx?forum=4513#67270

For version 5.0, you need to enable "Login Required" in the preset. For more infos, click here: http://www.flatcast.com/de/FcForum.aspx?forum=4513#4556 and scroll to "Login Required"

Regards
