Disclaimers and Privacy Settings For WordPress Website

I am using the premium theme TruePixel….In the process of putting up my website I am just wanting to know exactly what privacy measures, disclaimers, etc I need to put in place. My website it going to be a blog information site but also a social media platform using Buddypress as well as a forum using bbpress…I am just wanting to make sure all of my bases are covered and that I have all security measures in place…what all types of things do I need to make sure of this…I was going to put a disclaimer page, a Terms and Condition page, Privacy Policy as links on my footer…Could you please let me know for this type of site what else I may need to cover myself…in buddypress when people register it shows to include their email addresses…I know there is TrustE for sites as well as VeriSign…how do I go about getting these or do I need these?….This is my first website and want to make sure I am covering myself and doing everything correctly and where visitors will trust my site…also what type of malware and other types of security scanning do I need for a site like that? Any info would be greatly appreciated….Thanks,,Rhonda
