Prime anytime you want to do them, just yell. Mav says any level 50 could tank those two, so Brem would go. Hopefully Lynk is around because I would feel better about your toon's safety with a real Tank or perhaps we could talk Miltiades or Mav into Tanking for us.
But yeah, we will do it again soon if enough people are interested. Also not going to speak for everyone, but I'm pretty sure Lynk or I would go 90% of the time if you catch us on and free, so just yell (pretty sure the others would too, but don't want to volunterer anyone, but Lynk).
Personally I would like to see us do something as a guild at least once a month, but that could just be me.
