This question is part user experience, part engineering.
I am trying to find a nice, clean way to have a user communicate with my web page while they are on another web page. I have web services that will accept HTTP POST/GET, so AJAX and other asynchronous niceties are welcome - don't worry about the details of their communication, they can easily be modified to fit a solution.
The problem I'm running into lies within the user interaction. Ex., say the user is viewing a web page and they want to send my system the web site's URL. I would like it if they could do it while still looking at that page, and without too many "crazy clicks" - currently they have to go back over to my page and enter the information (as you can imagine this has tested horribly).
I have ruled out browser tool bars (easy to do in FF, but a lot of my users use IE) and local applications (they won't want to install Java or Adobe Air apps).
Have you ever solved a problem like this before, or do you have an idea of how I could solve it? Should I be looking at separate solutions for FF and IE (ex., a tool bar for FF and something else for IE)? Don't worry about Safari and Chrome, though a solution that supports them too would be nifty.
Thanks.
p.s. The user would have an account on my system already.
