Thanks for joining us, Mickie! You might want to make some of the changes I suggested to Leslie, such as having a cover high in the sidebar that highlights what your website offers, and have a link and mention of it in the welcome. If you can get a tab in the navigation bar, that is always helpful. Regarding security, there are some other plugs in you can get like Limit Log In Attempts and Wordfence. It is shocking when you see how many hackers or bots are trying to hack you on a daily basis. If you ever get hacked with malware, Sucuri is a good resource to bail you out. They will look into it immediately and were very easy to work with. If you find security is becoming an issue and you want to take even more precautions, you can also pay them something like $89 per year and they will check your site daily and fix it if they find anything.
If your site is ever acting strangely run it through those links I gave and it will tell you if there is malware.
