I desided to buy JBolo (although there is not any kind of demo or trial, out there!?!)
because of this site (Joomla! Extensions Directory)
What I mean? I saw the reviews here and I felt safe because of JBolo owner's replies.
I realized that he was caring about his reputation.
So if JBolo was worthless I should "punished" him with a bad review.
And, unluckily, a wrong happened! I had to wait 24 hours to be able to download JBolo, after I purchased with my credit card!
I convinced myself to wait until the day after.
After I installed JBolo, I umderstood that my choice was excellent!
But that, that impressed me was the fantastic support!!!
Thank all of you guys (JBolo's team, people who did a review here and ofcourse Joomla! Extensions Directory).
