I was looking for a newsletter and a smsinfo component. And Jnews is the only one to purpose extra field for registering form on the fly.
The installation was simple but I went in trouble with the validation process (it was my fault I registered the license for my local website) so I've been to the support page and I try the "Live support Chat" and then ... Whaou there was someone real !!! and very competant, in few minute everythings was right !
Since I use this component I'm really happy to discover new function and create newsletter in a breeze.
Really thank's !
