Website in operation needs Ryan's activity feed fixed for browsers. When an activity feed posting is made there is the option of adding a comment. A comment box drops down along with a submit and cancel button. On my site, this does not work for all browsers. On Mozilla sometimes works and other times shows box but will not allow input. IE does not show the submit / cancel buttons.
Knowledge of phpfox is a big advantage so there will not be a learning curve of how all the modules fit together.
