Someone PM me that they also intend to use it for business purposes and not for personal email.
What I meant that we use @sulit.com.ph for business purposes is that we represent our company using these email addresses. So anyone using this email is on-behalf of Sulit.com.ph.
Although I am not saying that members will do this, but we are trying to avoid misrepresentation that can have a critical effect to Sulit.com.ph in general.
Thanks for your understanding.
