I used precense, about 6 - 8 days not is normal

I am not happy with openfire is not normal, it takes one or two months to make a instant messenger
You know... you can't develop an instant messenger in just 2 weeks.
Spark has been developed over several years.
In my company we are working with XMPP since 2011 and a _prototypical_ Instant Messenging system took also some months.
