Welcome to the Q&A Forum

looks like you took care of the language issue from what I can tell xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-GB" lang="en-GB" dir="ltr"> what do you think about using the help desk in replacement for a forum? It is completely private that way you can have tickets to go out to whoever you are dealing with and none of it is indexed. I also believe that using WAF CloudProxy.Sucuri.net   allow you to white list customers whom  you trust this is an inexpensive WAF but a very effective one. I believe that would limit the user created spam to a minimum. Sincerely, Thomas
