I'm interesting in purchasing your plugin. First I've some questions:
1. If I buy the pro version, is it necessary to uninstall the standard version first?
2. Is it possible to use the chat with BuddyPress user names or is it necessary to use facebook, twitter or guest-accounts first?
3. Is there a translation file for German available?
4. Can I get the bp tinychat page plugin too as you offered in http://wordpress.org/support/topic/add-chat-bar-link-floating-at-the-bottom-of-the-page?replies=20 ?
Thanks for answering my questions!
