Right, so this confirms I have stopped receiving subscription alerts for quite a few threads now, which I am going to complain about to AppThemes.
Just checking in to see towers_1 has an advice, he is entitled to have his opinions about the product, and I have no problem with that. I agree there is a lot that could be improved in the plugin and I will soon start work on adding double opt-in feature. Your ideas are welcome and may be implemented as I find time, but the plugin works as advertised, if you have bought it and it is not useful to you in its current state, I feel sorry, but there are plenty of developers out there who you can pay and get it customised. Unfortunately, I do not have time for customisation work for the next few days, and in hindsight, I am happy not to have worked with towers_1 seeing as he makes a lot about my appearance which has no connection to the product in question.
