The willingness of our members to share with our friends is just another reason this place is what it is
When a thread is posted, it's an opening statement in a conversation...the rest just falls into place.
I think it veers off into a hijack when the replies get into a different subject altogether...like when somebody posts a thread of a mounted Encyclia and we all go ga-ga over it...and then start talking about where to get the best driftwood for mounting...which I am guilty of doing on occasion
