USNA buyout I need advice

[nanamom]

I invest through Sharebuilder. I received a notice in the mail that a company (or person) wants to buy my stock at 26.00 per share which is slightly higher than todays market price. I believe is it legit since I have seen articles that this was to start. From what I understand it is a public company and that is to change. Someone wants to acquire all the stock. I don't know if I should sell or not. I would reinvest the money so that isn't an issue but has anyone experience with this? Will they offer more later or will the stock go down?
Any advice or experience would be appreciated.

more than likely you received something about voting your shares (sell or not sell). If majority votes to sell, does not matter what you decide.
