I finally have found the time to code up a little utility. Its' purpose is to enable someone to log on to a MikroTik RouterOS based HotSpot without having to open a browser and enter their credentials there. There was some demand for such a utility in the forum (swanto and others), so I promised to hack together something - here you are. It's still a preview version - for the RouterOS community to test and comment on.
You can download it from http://cmit.de/downloads/hotspot-logintool.zip (197 kB). It's small (200 kB) and doesn't need any installation. Please check the ReadMe.txt inside the zip file.
Feedback is warmly welcome, more about that (and where to send your feedback to) is in the ReadMe.txt, too.
