Welcome to the Beta Sigma Phi board!
I'm a relatively young new member to Beta, and started a chapter of my own....hard work....but totally worth it. it's almost completely comprised of collegiate women. We call starting a new chapter "Friendly Venturing". If you have six like minded friends, you can also Friendly Venture too.
In answer to your question regarding the two chapters:
If both chapters are listed on the chapter lookup on the International website, then I'd assume they were still active.
I can tell by the chapter's names that they are higher degreed chapters, meaning that they were started by women who had been Beta Sigma Phi sisters for at least several years.
Other than that, I'm unsure of other information about them.
