PS: as I give support for free, I’d really appreciate a vote for my plugin on http://wordpress.org/support/view/plugin-reviews/leaflet-maps-marker 😉
can you give me an time frame for adding users to add markers?
how can I contact you out of the forum to discuss price and idea for this request?
sorry, but cant give you an exact timeframe for now. I am currently working hard on a pro version which will be available within q1/2013. One of the first features will be adding markers by users via frontend.
