Sorry for the delayed reply on this and thanks for the feedback so far..
(I've actually re-done the look and feel to match our current audience 10-20 year olds..
http://www.signaturebar.com)
In terms of revenue yes its intented to make money, at the end of the day its a free service and although its very easy to make userbars and signatures there are some who dont know how or are just learning (Or plain lazy lol )
The site has a multitude of objectives which I have listed below..
1.) A hang out place for kids (Yes because its kids mainly that are into sigs and bars) to learn and showoff there work.
2.) A place to stick all your sigs and userbars in one place (i.e. FREE hosting)
3.) We offer a number of animator and countdown tools (These are actually very popular)
4.) I have re-deisgned the site with a new look and feel and we've had a huge uptake compared to before, I guess it just seems more professional and easier to navigate.
5.) We have opened the forums up for showing off other art work too e.g. wallpapers etc etc and from this we actually had some offer to do banners and business logos. (Although my designers work for FREE they will now get paid to do the business logos, banners, ebay templates, which of course keeps them motivated )
Sorry for the long update and once again thanks for your feedback and views 1
