When you register a domain, you opt to register it for a set number of years. For QuranConnection.com this will expire within 18 months after which it will not be renewed by the site creators/hosts (myself and others). Thus, the site will not exist after that.
Of course, others could register it and create/run such a site - if anyone is interested in that, let me know.
People can do the same type of networking on forums and facebook etc so the QC site is not as crucial as it was when it was first conceived (before facebook even existed I might add). For example, there are several quran based islam forums and many facebook groups now.
The chat link will function until the site expires: http://quranconnection.com/chat.html
After which is a simple process to change the chat link and let people on here know etc.
mohf I have sent you a request.
