Thanks, I am going to update the function names as soon as possible.
I didn't replace them in the first release intentionally, as I thought the plugins would have been excluding each other and sharing the settings.
After the porting to MooTools, almost everything has been kept untouched.
But I'm planning to add some further options in a near future release, like a default avatar (the same as in the comments settings), custom sizes, etc...
Obviously this would require to redefine the functions, but if you're interested I could send you the code.
Anyway, if you're about to implement MooTools, I'm going to discontinue the plugin, otherwise we may arrange a sync release in the schedule.
Thanks again, let me know
