Glad to hear it's working well so far. We did exhaustive testing in a lot of different cases. Also, we released the SCLogin module back in March using jQuery to test the 'conflict waters' and see how things would go. Joomla 3.x, again, is much simpler because of the shared jQuery available. Man, I wish Joomla 2.5 had such an option.. which, is why we've used Mootools until now.
Anyways, should you run into anything or have any comments or feedback in general, definitely let us know!
Thanks,
Alex
