If you need support from Yola please contact us via firstname.lastname@example.org or make use of our live chat service! We are working on a new approach to community-based support and during this transition period we are not adding any new threads to this forum. Many thanks to everyone who has participated over the years and we look forward to unveiling a new peer-to-peer support system soon!
Meebo is not built by Yola, but they have a tutorial that you can use to moderate your chatroom to get rid of unwanted messages and ban people if necessary. Here is the link: Moderating a Room.
If you need any other help with your Meebo chatroom, you can send a request on their Contact Support page.
