I have been using youjoomla for quite a while now.
I have setup Many, Many websites.
All work effortlessly, and perfectly.
Some of my sites have over 20,000 unique visitors a day.
The only problem I ever had, was that my hosting provider turned off my site because I was getting too much traffic and using up too much of the servers resources.
If you want a very fast website, that is deep in function, with a huge amount of endless possibilities.. I would suggest you team up Joomla with Youjoomla.
This is an unbeatable union.
These guys are fast at creating New templates each month. Each month we see a brand new look and feel, and they are all great.
Being a member of Youjoomla is kinda like having Christmas every month.. as we get to log in and open a new package,(A new design) Every Month! Very exciting if you are one who sets up many websites on a regular basis.
Thank you to the staff at Youjoomla, My hat goes off to you!
Just me... ps One of my sites http://www.cfcamerica.org
