Scratch

As you know (my sig    ) that I am making a mod called Kitcat. Kitcat will have a whole new sort of blocks-ones that interact with the Kitcat site. (ex. buy stuff, comment on project, wwm, etc.)
~to make this more secure, I need an auto pop up when you open kitcat that will ask for your username/password, or work offline. I know that this is possible because both Panther , BYOB,(beleive it or not) and Bingo (hint hint hint, ls97     ) do this. In panther, it shows current updates from a server. BYOB checks for updates, and Bingo shows news. WILL ONE OF THESE DEVS OR NICE PEOPLE EXPLAIN HOW TO DO THIS??????????
