Thank you for your feedback guys.

@Kobra: You made my day with the first comment.

About your suggestion about editing the htaccess file, that's a good one. I am thinking of implementing what you suggested, but instead of putting my plain IP, I will put a subnet mask to allow the whole IP range covered by my ISP. All hacking attempts come from outside my Country (Puerto Rico) and my ISP only covers part of the Country, filtering the whole internet down to about several hundred thousands of users. That will decrease the risk largely and I will not need to be constantly editing my htcaccess file.

Thank you for that!

@Trees2wood: Yes, I've been thinking about it, but I am reluctant about someone doing it and having access to everything, instead of only building some type of plugin or script that could be adapted to what I need in the admin area, which is something I would gladly pay for. Thank you for your suggestion, it also appreciated.

Best regards
