Absolutely Deb...
For those that are new to this site, you may think this chat software is new, but its actually not. We used to have version 5 of this exact software installed here, running live video chat, and members got a lot out of it. As stated elsewhere, the issue was expense and technology at that time... video was just new to the web and the cost vs. outcome wasn't the best.
For those who briefly used it already, you would have seen its somewhat impressive to live video through it now, especially those who used the prior version here, in comparison. Very fast and technology is the key to that. Now the technology support it as a far superior method of communication, I have reimplemented here.
Issues Raised
These very issues were raised first time round... and we had little to no problems with members and the chat. This version happens to have far more capabilities than ever before. Users can report users and place a custom message within the report to tell me the issue.
All staff have unrestricted access into all chats, whether private, public or password protected, they can enter every room, visibly or invisibly, monitoring chats. So even if two users registered here, did not participate on the forum, but only used the chat, they would be discovered quickly enough through repetitive behaviour and banned from the forum.
Staff can also kick, gag and time base ban from the chat only, per user. So if you abuse chat, you can still have forum access, but not chat. If you get banned from the forum though, you lose chat automatically, and the forum has some pretty good spam prevention tools in place for finding deceptive users and spammers.
