Hi. Though this is the "Ask Kassandra" forum, it doesn't mean only Kassandra can answer!!
This is a public message board, so feel free to jump in there at any time and share your thoughts, feelings and insight, or ask further questions.
And (as far as I, personally, am concerned) commenting on "old" posts is perfectly fine. If you're inspired to question or comment on something, then obviously the information is still relevant in some way.
Regarding my turnaround time, I should have my responses to your questions (both your private messages, and postings here in this forum) sent or posted about 24 to 48 hours after I receive them. Thanks.
