Can an agent do wholesaling too?

[James Thiel]

I'm more interested in wholesaling, but recently got my RE license thinking I may become an traditional listing/buyer's agent.  Can I do both?  Must I disclose to sellers whose homes I plan to wholesale) that I'm a licensed agent?  Should I put that disclosure on my direct mail/website?  I ask because I actually like the approach to wholesaling that others have used where they state "we are not RE agents, but rather investors".  Look forward to everyone's responses/input. Thanks!
